President Joe Biden is losing the support of those who once supported the former President after flipping them two years ago. A poll analyzing voters who backed former President Donald Trump in 2016 before casting a ballot for Biden in 2020 has found just 3 in 10 would do it again. [tweet_embed] May 14, 2022[/tweet_embed] The poll, published by Republican public opinion research firm J.L. Partners, also found 1 in 5 of the same voters graded Biden as performing "very well" as President. Voters older than 65 were more critical of Biden, with 7% repeating the assessment. J.L. Partners founder James Johnson, former British Prime Minister Theresa May's chief pollster, indicates that so-called purple voters will be crucial in November's midterm elections and the next presidential cycle, estimating that approximately 4 million people are members of the group. For instance, the poll found more than 1 in 4 planning to vote Republican this fall, urged by liberal positions on the removal of statues and monuments, the use of gender pronouns, race protests, and canceled culture. About 68% remained committed to Democrats. Johnson, too, ties Biden's and Democrats' declining purple voter support to disappointment over their handling of the economy and immigration policy and their promise to unite the country.

The poll also demonstrates a troublesome trend for Vice President Kamala Harris. Roughly 15% of purple voters considered Harris to be doing "very well" as Biden's understudy. However, at the same time, 8% of purple voters would back Trump in a 2024 Biden-Trump rematch. Another 68% would back Biden. “A focus on the last election strongly deters them and, come November, could cost those candidates who are currently ramping up their rhetoric for the primaries," Johnson said. "The GOP would do much better targeting their message on inflation, as well as crime and the border.” Nikki Haley, former U.N. ambassador and South Carolina governor, and onetime Vice President Mike Pence emerged as purple voters' most popular poll-tested White House candidates. Yet Haley and Pence were both overshadowed by Rep. Liz Cheney (R-WY) and Secretary of Transportation Pete Buttigieg.

Partners polled a sample of 663 purple voters online between Jan. 17 and April 2022. The firm's results have a margin of error of plus or minus 3.7 percentage points. Its previous U.S. work includes Arizona's 2022 Republican gubernatorial contest.
