There is still a few Freepers (I'm not one) that believes he's a conservative.
Mine is that he was buddies with communists... much like Horowitz in his youth. Got disenchanted for some reason or another... and became a simple rabble-rouser... a sawed-off hothead with no affiliations.
The difference between Weiner and Horowitz is that David knows American history... Weiner just tells you that he does.
