From the article:
Ben Smith, who lives in suburban Larimer County, Colorado, north of Denver, said he reluctantly registered as a Republican earlier in the year after becoming increasingly concerned about the
Democrats’ support in some localities for mandatory COVID-19 vaccines, the party’s inability to quell violent crime and
its frequent focus on racial justice.
also From the article:
But over the last year, roughly two-thirds of the 1.7 million voters who changed their party affiliation shifted to the Republican Party. In all, more than 1 million people became Republicans compared to about
630,000 who became Democrats.
The broad migration of more than 1 million voters, a small portion of the overall U.S. electorate, does not ensure widespread Republican success in the November midterm elections, which will determine control of Congress and dozens of governorships. Democrats are hoping the Supreme Court’s decision on Friday to overrule Roe v. Wade will energize supporters, particularly in the suburbs, ahead of the midterms.
So, nearly a million people changed their political affiliation to democrat which sort of nullifies the million people that changed their political affiliation to republicans.
What the democrats need to do is focus their efforts on getting their base out.
