<p>The old political proverb that “all politics is local” is becoming less relevant as candidates increasingly present themselves on a national stage rather than focusing solely on their state constituents.</p>
<p>Candidates running for Congress, governor, and lower offices in the 2026 midterm elections are campaigning on issues that extend beyond state lines.</p>
<p>A controversy in Michigan can influence perceptions in Georgia. A proposed data center outside a small town in Ohio can become part of a national debate. Endorsements or associations with figures such as President Donald Trump, the Democratic Socialists of America, or world leaders can define candidates before voters learn much else about them.</p>
<p>This trend reflects the broader nationalization of American politics, which has diminished the independence candidates once had from their political parties. This shift is particularly evident in the 2026 midterm elections, where candidates must balance national political identities that can attract attention, donations, and primary support with local issues that could determine their success in November.</p>
<p>“In the earlier era, it was the case that while people were aware of what was going on in politics nationally, they also prioritized and prized sort of their own close-to-home issues more than anything else,” said Ethan Porter, an associate professor of media and public affairs and political science at George Washington University.</p>
<p>Those local concerns have not disappeared, Porter noted, but they are increasingly “eclipsed” by voters’ broader political commitments.</p>
<h2>The Letter Next to the Name</h2>
<p>For candidates in this year’s elections, one significant consequence is the challenge of distancing themselves from their party affiliation.</p>
<p>“Two or three decades ago it was much more straightforward to identify with a party but also declare yourself independent of that party,” Porter said.</p>
<p>This has become more complicated as national media, social media, and increasingly polarized parties have created political brands that extend across state lines.</p>
<p>“The first thing people notice is whether there’s a D or an R next to a candidate’s name,” Porter said, “and that will deeply impact how that candidate is perceived.”</p>
<p>This dynamic is particularly pronounced in the Trump-era Republican Party, where candidates often seek the president’s endorsement, and loyalty to Trump has become a dividing line in Republican primaries. Porter stated that Trump has effectively become synonymous with the party.</p>
<p>For instance, in Texas’s GOP primary runoff election between Sen. John Cornyn (R-TX) and Attorney General Ken Paxton, Trump’s endorsement was pivotal. The president deemed Cornyn not aligned enough with his MAGA movement, endorsing Paxton instead.</p>
<p>Democrats face a similar situation.</p>
<p>The rise of socialist candidates has created a national political identity that candidates can adopt, but it can also be used against them. These candidates can campaign as both Democrats and critics of the Democratic establishment.</p>
<p>Porter suggested that part of the appeal may stem from voters' attraction to politicians willing to challenge their own party.</p>
<p>“They are both of the party but not of the party,” Porter said of socialist candidates. “They’re outsiders to the party, and people like that.”</p>
<h2>National Politics Brings National Money</h2>
<p>There is also a practical reason for congressional candidates to address issues far beyond their districts: individuals in those areas can contribute financially to their campaigns.</p>
<p>Online fundraising and social media have significantly expanded campaign potential.</p>
<p>A candidate who takes a provocative stance on a national policy can generate news coverage, social media engagement, and donations from across the country, even from those who will never vote for them.</p>
<p>For example, Michigan Democratic Senate nominee Abdul el Sayed has taken a firm stance opposing Israel. While residents of Michigan may prioritize local economic issues, his position garnered national attention and attracted donations from across the country.</p>
<p>Porter noted that candidates had limited ability to appeal outside their states two decades ago.</p>
<p>“That’s just obviously no longer the case,” he said. “Candidates are constantly appealing to co-partisans out of state.”</p>
<p>He also pointed out that the decline of local media has reinforced the incentive to campaign nationally.</p>
<p>“It can be hard to actually sort of get in the limelight based on local issues,” he said.</p>
<p>In contrast, a candidate addressing a major national controversy can quickly enter an ongoing political conversation.</p>
<p>“The worst thing you can be as a candidate, especially for a competitive race, is ignored by voters and the media,” Porter said.</p>
<h2>Winning the Primary, Surviving the General</h2>
<p>Nationalization presents significant challenges during the transition from primary to general elections.</p>
<p>Primary voters tend to be more partisan and ideologically committed, rewarding candidates who take firm positions on issues that resonate with their party. However, the broader electorate that turns out in November can look quite different.</p>
<p>“Candidates in both parties are going to be incentivized during primaries to appeal to the most die-hard partisans,” Porter said, cautioning that “general elections are not won by die-hard partisans” but by voters closer to the political center.</p>
<p>This can leave candidates attempting to distance themselves from political identities they have built during the primaries.</p>
<p>Michigan has provided a clear example this cycle, as el Sayed seeks to appeal to independents and centrist Republicans after taking partisan stances. He emerged from a primary election where disputes over Israel, pro-Israel campaign spending, and associations with controversial figures became significant lines of attack.</p>
<p>Those issues could mobilize ideologically aligned voters nationally, but he now faces competition for a broader electorate concerned with Michigan’s economy, industry, and cost of living.</p>
<p>Republicans encounter a similar dilemma.</p>
<p>Trump’s endorsement can carry significant weight in a Republican primary, but closely aligning a campaign with the president poses risks in areas where his popularity is lower among the general electorate.</p>
<p>Porter stated that nationalizing a campaign can be beneficial for fundraising and winning a primary.</p>
<p>“But in doing so, you might have taken provocative, divisive stances on issues that are going to be much less appealing to the actual general electorate you will be facing in the general election,” he said.</p>
<h2>When Local Issues Become National Issues</h2>
<p>Nationalization does not solely originate from Washington.</p>
<p>The 2026 midterm elections also illustrate how issues that start as local disputes can become part of national political identities.</p>
<p>Data centers serve as an example.</p>
<p>The rapid expansion of AI infrastructure has brought disputes over electricity costs, water consumption, development, and land use into races nationwide. A voter may not have a data center proposed in their area but can still encounter advertisements, videos, and political arguments originating from distant communities.</p>
<p>“We’re in an era where political advertising is not localized at all,” Porter said. “You might not have a data center in your backyard, but you might see a persuasive ad.”</p>
<p>Whether the issue ultimately develops a lasting partisan identity remains uncertain.</p>
<p>Porter suggested that opposition to data centers could instead reflect anti-incumbent sentiment, with voters blaming the party in power when dissatisfied with development or economic conditions.</p>
<p>This situation illustrates how nationalization has transformed not only the way candidates campaign but also the issues they address. A conflict that begins over a project in one community can provide campaign language for candidates nationwide, as national political divisions increasingly shape voters' understanding of local issues.</p>
<p>For candidates navigating the midterm elections, this leaves little distinction between what constitutes a local issue and what is considered a national one.</p>
