Business Insider puts a fine point on it. Romney and Republican super PACs are raising tons of money and should be able to give him a leg up in the final months of the campaign.
Both Romney and Obama have been fundraising consistently for months. But Romney has kept his head down and his account flush, and didn't try to compete with the Olympics, the Conventions, or the recent mediocre press. He was competent enough to realize that the Obama campaign had to hemorrhage cash in order to maintain their numbers.
And now, he's got a massive upper hand, which very few people are talking about. Once he and his surrogates carpet bomb the swing states with adverts, by shear mathematics Obama will take a small but predictable dive in the polls. In the middle of October, Mitt starts looking like a contender again.
The past few weeks of Mediocre Mitt are about to end. He's got more resources than the Obama campaign, and his ability to find cheap media markets and flex his muscle are just coming to the fore. This, plus a few more bad economic months, and he's in the White House.
