Over 1 million U.S. voters in 43 states have fled the Democratic Party since 2021 and registered as Republicans, according to a new report.

Republicans have gained major ground in suburban counties, according to the voter registration data examined by The Associated Press, as well as “in virtually every region of the country.” The findings come almost four months before the midterm elections in November, which a bipartisan swath of pundits has deemed a probable “red wave” in part due to messaging failures among the left.

“While Democrats may see a slight enthusiasm bump following the Supreme Court’s decision on abortion, it’s highly unlikely they’ll be able to sustain that for the next five months,” Andy Surabian, a Republican strategist, told The Daily Caller News Foundation.

Data for roughly 1.7 million voters who switched political parties was analyzed by the AP. The data, which according to the outlet comes from the political firm L2, reportedly shows that around two-thirds of the 1.7 million voters became Republicans — while only about 630,000 voters became Democrats.
