This is interesting. We had known before this quarter that Romney had spent about $17 million of his own fortune on this campaign – he had a pretty darn impressive fundraising haul earlier in the cycle — and the AP now says:

Romney’s advisers had given him several options, ranging from $1 million in ads to $7 million in ads for an expensive multistate effort. It was not immediately clear how much money Romney was willing to spend – or whether the multimillionaire would dip into his own bank account again. He already has poured at least $40 million into his presidential campaign.

Is the AP more or less confirming Romney has spent $23 million of his own money in the last three months? Or is that just the floor?
