WASHINGTON (AP) – Republicans have gained ground on Democrats in registering voters in three battleground states and kept their razor-thin advantage in Iowa. That’s encouraging news for Donald Trump eight weeks before Election Day. Data compiled by The Associated Press show that Republicans added hundreds of thousands of voters to the rolls since 2012 in states including Florida and Arizona, and narrowed the gap in North Carolina. In Iowa, Republicans prevented Democrats from surpassing them, aided by a court ruling upholding a ban on voting by ex-felons, who often register as Democrats.

As Election Day approaches, voter registration drives are in full swing. The latest registration numbers aren’t an assurance of new voters for Trump. But the figures, when available, offer important clues as to how each party stands.
