Money in politics works... but only to an extent. If a candidate has already spent so much, then it doesn't matter how much more money they spend: for example, Jon Corzine spent $50 Million for a Senate seat he only won by 3 (and outspent his Republican by a margin of, I think, 10-1). On the other side: If a candidate is so doomed, money can't fix that. Blanche Lincoln outspent whoever the Republican was by 9-1, and lost by one of the largest margins an incumbent has ever lost by.
However, no candidate is doomed or has already spent beyond a crazy amaount here, so money is fairplay, but that doesn't necessairly mean the candidate with the most money will win.
Well, seriously, I don't think money has no influence as well.
I mean, it only works when people don't have any name recognition. The GA primary, the PA primary,... All of them didn't have a great name recognition, that's why big money worked so well for Wolf and Perdue.
But in some other states, it doesn't work at all. I mean, Mark Pryor, even if Afd seems to have ended their attack, he has really been extremely attacked, and no change for him basically if we compare with his situation 6 month ago. Simply because Pryor has a great namer recognition (senator + his father)!
