I watched about 15 minutes of one of his “routines”. He has some deep psychological issues in regards to Conservatives. If I remember correctly he may have grown up in a Conservative home (I could be wrong). So basically he is like much of Hollywood, he just never grew out of the rebellious adolescent phase. On top of that he had an ego the size of Obama. That pretty much comes across in the excerpts posted above.
His uncle was a Democrat Congressman who lost reelection to Jesse Helms.
