• National polls show they have modest edge over Republicans

• Congress serves as check on presidential powers

WASHINGTON: National polling suggests that Democ­rats hold a modest advantage over Republicans ahead of the 2026 US mid-term elections, a contest that could significantly affect President Donald Trump’s ability to advance his agenda during the second half of his term.

A compilation of recent generic congressional ballot surveys, published by The New York Times on Sunday, shows Democrats leading in most national polls by margins ranging from one to six percentage points, with one survey showing a larger Democ­ratic advantage. The generic ballot asks voters which party they would support for Cong­ress without naming specific candidates.
