It is a well known phenomenon that a massive number of Southern Democratic politicians switched to the Republican Party in the years and decades after the passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965 under the administration of President Lyndon B. Johnson.
But it would be instructive to trace those Democrats, in their younger days, who were not Southerners, who made the switch from the Democratic Party to the Republican Party.
Following is a list of the more prominent such examples, numbering eleven.
In the early 1960s, actor Ronald Reagan, who had been a liberal Democrat and union leader in his younger days, became a Republican, influenced by his wife Nancy’s father, and soon was recruited by Southern California businessmen to run for Governor, and that was the beginning of an amazing transformation in views.
Donald Trump originally was a Democrat, and contributed to New York City and State Democrats, became an Independent, then went back to the Democrats, and finally allied himself with the Republican Party in 2011 and after.
