More than 100,000 Republicans left the party since January
After the pro-Trump riots, more than 12,000 registered Republicans left the party in Pennsylvania, with some 33,000 leaving the GOP in California and more than 10,000 Republicans changing their affiliation in Arizona. Both Arizona and Pennsylvania were hotly contested swing states in the last election, each decided by thousands of votes.
One of those voters who changed their party affiliation was Juan Nunez, a 56-year-old Army veteran from Mechanicsburg, Pennsylvania, who told the Times that that the insurrection "broke [his] heart" and was directly responsible for him fleeing the Republican Party.
Earlier this month, Reuters reported that several former Republican officials had said they would leave the party in the wake of the Jan. 6 attack, in which five people died. The outlet cited a number of former high-ranking officials from the George W. Bush administration who said they could no longer recognize their party and argued that current GOP lawmakers didn't do enough to denounce Trump's baseless election fraud claims. "The Republican Party as I knew it no longer exists," Jimmy Gurulé, who served as the undersecretary of the treasury for terrorism and financial intelligence under Bush, told Reuters. "I'd call it the cult of Trump."
