The difference is -- starting in the 60's, the party became a toxic sandbox that attracted ONLY the worse factions in American society.
Think through all the "groups" in America that repulse you, and I'd bet granny's Rum bearing cow -- they look to the "Democrat" party for their welcome and power - rather than some tiny ineffective party of their own...
A small list of the Democrat "base": Lazy leaches, Unions - Most especially Teachers and Civil Service Employees, Welfare cows and pimps, Socialists, Fascists, Communists, Marxists, Anti-America kooks of all stripes, Homosexual Activists, Abortion Activists, NAACP, "teachers", Felons - both in and out of prison, etc, etc, etc......
Hell, there are even folks already in the cemetery that STILL vote Democrat with regularity!!!
The two possible explanations for the tendency of the dead to vote Democrat - is the living are becoming more aware or the dead is how the Democrats wish to see all Americans.
The DNC leadership (Dr. "Screaming" Dean) and most Democrat politicians have declined in quality to reflect their constituency -- otherwise they COULDN'T get elected.
Semper Fi
The evil rat party must be utterly destroyed.
