I think a lot of Hogan's problems stem from Bischoff. Hogan was probably a legitimate good guy until Bischoff got in his ear and rode his coat tails. That's not to say he wasn't political back in the day. Anybody who gets to the top is political. But even the Hulkamania gimmic wasn't completely just a gimmick. I think plenty of that was legitimately who Terry Bolea was then.
Now his family has fallen apart and he only has some of his old cronies like the Nasty Boys, Jimmy Hart, and Nash that are still his friends. Never say never about a reconciliation with Vince though.
At the end of the day Bischoff seems to be more the cancer than Hogan.
Also, say what you will about the man today, how he buried people in WCW and allegedly is burying people in TNA (although I think Ken Anderson and Jeff Hardy while not TNA originals, are two guys Bischoff typically doesn't seem to like getting over as champion and could be proof that maybe things are different this time around), the wrestling industry wouldn't be where it is today without him.
He'll always remain the single most important wrestling icon in professional wrestling history. He put WWF on the map back in the 80s and made it the world wide powerhouse it still is today (Austin rescued it from the Monday Night Wars yes, but without Hogan there would be no Wrestlemania and no WWF to rescue). He also was the biggest driving force talent wise behind WCW putting Vince on the ropes for over a year and a half in the ratings wars.
At the end of the day, his personal problems and character aside, there's no denying he's the single greatest and most important wrestler in the history of the industry. Flair, his only contemporary in that area, even admits as such in past interviews you can find on one of the older Hogan DVD sets. He wasn't the best wrestler, or the best on the mic, but as far as the total package goes nobody's above him.
