If you want to blame anyone, blame his idiot campaign manager.
Hunter’s biggest problem was name recognition. Talk to most people about him and you get “Hunter who?” You can’t even say “He’s the guy that did x,” since thanks to the media nothing he’s done has ever registered on the general consciousness.
He (or his campaign manager, more likely) didn’t have or didn’t spend the money to get over that problem. He should have been spending money in a national campaign from the day he declared in 2007. He didn’t (and yes, I sent him $250).
That’s why he’s had to bail out.
