The REPUBLICAN PARTY was FOUNDED as the ANTI-SLAVERY PARTY to oppose the pro-slavery Democrat Party.
The Republican Congress passed the Civil Rights Laws of the 1960s and 1970s.
In the 21st century, the Democrat Party made the Grand Dragon (or whatever they call it) of the Ku Klux Klan "Majority Leader" of the Democrat-controlled U.S. Senate.
The Republican Party has always been respectable.
The Democrat Party has always been vile.
Actually, the Democrats controlled the Congress during the ‘60s and ‘70s.
