If Trump Is So Unpopular, Why Does He Still Dominate the GOP? [View all]
President Trumps approval ratings have fallen to some of their lowest levels since his return to the White House. Yet despite his weak national standing, Trump-backed candidates continue to win GOP primaries, and Republicans seen as insufficiently loyal to the president are increasingly finding themselves pushed to the political sidelines.
For many Americans, that disconnect can seem puzzling: If Trump is so unpopular nationally, why does he still hold such enormous influence within the Republican Party?
Political analysts say the answer lies in a combination of forces reshaping modern American politics: deep partisan polarization, Trumps enduring grip on the GOP base, conservative media ecosystems, and an electorate that increasingly views politics through the lens of party identity rather than personal approval of a single politician.
The result is a political environment in which weak national approval ratings do not necessarily weaken the presidents standing within his own party, particularly in primary elections dominated by highly engaged partisan voters.
