In the days after the Jan. 6 attack on the Capitol, the phone lines and websites of local election officials across the country were jumping: Tens of thousands of Republicans were calling or logging on to switch their party affiliations.
In California, more than 33,000 registered Republicans left the party during the three weeks after the Washington riot. In Pennsylvania, more than 12,000 voters left the G.O.P. in the past month, and more than 10,000 Republicans changed their registration in Arizona.
An analysis of January voting records by The New York Times found that nearly 140,000 Republicans had quit the party in 25 states that had readily available data (19 states do not have registration by party). Voting experts said the data indicated a stronger-than-usual flight from a political party after a presidential election, as well as the potential start of a damaging period for G.O.P. registrations as voters recoil from the Capitol violence and its fallout.
