Here are a couple of those more conservative Democrats I am incredibly proud have been left behind by today's Democratic Party. Notice that I used the correct name of the party, which most conservatives don't seem to be able to.
1. David Duke
Duke unsuccessfully stood as Democratic candidate for state legislature during the 1970s and 1980s, culminating in his campaign for the 1988 Democratic presidential nomination. After failing to gain any traction within the Democratic Party, Duke left and successfully gained the presidential nomination of the minor Populist Party.
2. George Wallace
George Corley Wallace Jr. (August 25, 1919 – September 13, 1998) was an American Democratic politician who served as the 45th Governor of Alabama for four terms. He is best remembered for his staunch segregationist and populist views
Can you please provide any support to your claim that Joe Biden is apparently too far left from the core Democratic past historical position in this country. Can you please show me how far left of FDR, JFK, and LBJ Joe Biden is? Those last 3 mentioned Democrats all led this country to a fairer, more equal, and more compassionate way than the Republican Party has thought of since prior to Nixon's Southern strategy of 1968. It is my personal observation that it is the Republican Party that has veered off of its path to the very far right of what it used to be. Many if not most conservative Democrats left the party to join the Republican Party which now should be renamed the Fascist Party of Trump.
