He's lying? Well, let's see.
Which Dixiecrats defected to the Republican Party? Jesse Helms, Strom Thurmand, and Mills Godwin, Jr. Quite an indictment.
But, consider this:
Who started the KKK? Democrats.
Which Party passed the Jim Crow laws? Democrat.
Which Party was Thomas Gore in at the end of his career? Democrat.
What Party was Robert Byrd in at the end of his career.? Same one he started with, the Democrats.
What Party was Gov William H. Murray a part of? Democrat.
What Party was home to Senator Spessard Holland? Democrat.
Dixiecrat Sam Ervin was a Democrat for life.
As was Senator Russell Long.
And Richard Russell.
And Olin Johnston.
And Lister Hill.
And John Stennis John Sparkman, John McClellan, James Eastland, Herman Talmadge, Herbert Walters, Harry F. Byrd, George Smathers, Frank Dixon, Fielding Wright, Everett Jordan, Benjamin Laney, Allen Ellender, AND Willis Robertson remained in the Democratic Party for their entire lives.
In fact, 93% of the Dixiecrats went back to the Democratic Party and remained their for the rest of their lives. You should have looked it up, but you didn't. Instead, you made a fool of yourself by posting a less than credible claim. Sucks to be you.
