The Democratic primary, or as many refer to it, our long national nightmare, will be remembered for a lot of reasons. One of the biggest — literally — is the amount of money spent.

Obama and Clinton have spent a combined $110 million on TV ads to this point; we’ve had a race that’s literally gone on since last summer for ad spending,” said Evan Tracey of TNS Media Intelligence/Campaign Media Analysis Group…

“We’re beyond what has been record spending in previous presidential nomination campaigns. John Kerry spent close to $20 million to get the nomination four years ago. Barack Obama’s already approaching $70 million.”

$50 million more than four years ago? In the primary? But wait, it’s not over yet.

Meanwhile, John McCain continues to be the main beneficiary of this wasting of Democratic bucks. The big question is, will Clinton or Obama be able to keep going back to their respective wells of financing? At some point — and $4 per gallon gas might be that point — people just run out of extra money.
