I agree with this. I cannot rejoice in the radicalization of the Democratic Party with the likes of Dean and Michael Moore. I'd rather the opposition were that of Truman and JFK. At least they didn't hate America.
It may have started out a sheer opportunism, but the Communist tradition is deep in the Party.
Truman was a machine politician from the Midwest and JFK was a response to Eisenhower at a time when the Democrat Party was viewed as being in the process of turning Red. It was less a rational heart felt response from the Democrats than a shrewd understanding of the electorate by the media organization of Joe Kennedy in JFKs case. DO not forget that LBJ was his VP.
The Democrats embraced JKK because of media manipulation by Joe, treacly sentimentality and some judicious lubricating of palms by the Kennedy political machine. Had Truman not been in the White house at the time, Wallace would have surely got the nomination. The GOP has never really called them out on this and this is unfortunate. It appears that the only way to bring this to light is through politics as the intellectual domain is controlled almost exclusively by the Democrats.
