Nobody had Romney’s money.
Romney had more money, more supporters, and better organization.
One can complain about Romney's scorched-earth rhetoric against Gingrich and others (to say nothing of his own ideological fudgings and missteps) but Romney didn't win on money alone. It was also man-power, hustle, discipline, and brains.
Money isn’t enough. Romney surived a 4 year smear campaign by people who were doing to him what they accused him of doing. It was very methodial. Romney is a tough fighter, a good man. Some people just refuse to see it cause they had their own agenda. This is the first time in a long time the Republican Primary voters got a really tough fighter who didn’t get it handed to him cause of some backroom deal, contrary to all that bull about him being the Establishment pick. There was a concerted effort to stop Romney at all costs, and it fell flat cause Romney is as smart as he is tough. A person doesn’t have to show their hand to be a tough fighter, in fact, the really good fighers don’t. The Republican party is very lucky this time, despite all the efforts to stop Romney. This is the first time in a long time, we have gotten a nominee who the powers that be tried to stop at all costs and failed, That includes Fox News and some others you worship.
Also, nobody had his meanness nor his unscrupulous tactics.
