Other Democratic candidates have made the same point, noting that Edwards would have to cap spending at $50.9-million during the primary period. That period begins Jan. 1, 2008, and formally ends at the party convention next August.
Critics argue that if Edwards were the nominee, presumably in the spring, he wouldn't have enough money left to defend against Republican attacks over the summer.
That's not entirely true.
First, it's incorrect to categorically say Edwards wouldn't be able to raise money between the primaries and the nomination. If Edwards' spending was short of the $50.9-million cap after the primaries, there's nothing in federal regulations that would prevent him from raising more primary money.
But let's assume the predictions are true that the current campaign cycle will break spending records.
Let's say Edwards spends all the way up to the $50.9-million cap on his way to becoming the presumptive nominee. Yes, the rules would prevent his campaign from spending any more at that point. But is he automatically disadvantaged, as Richardson suggests?
Richardson's statement does not consider that the Democratic Party could spend millions on a summer campaign if a clear nominee emerged by then. Independent groups and individuals also could chip in.
Consider the last presidential election. Total spending by the parties, independent groups and individuals on behalf of candidates totaled $192.4-million in 2004 — up from $14.7-million in 2000.
What's more, Edwards could help raise money for the party, which could "spend unlimited funds on his behalf," said Steve Weissman, associate director for policy at The Campaign Finance Institute.
"So it's not exactly true that Edwards would have no resources," he said.
The caveat: The law sets a limit on how much money the party and Edwards could spend while coordinating their efforts. The bulk of the money would have to be spent without coordination.
Not being able to coordinate with the party can be a less efficient way to operate, Weissman said. "It would be more difficult for Edwards," he said, "but I wouldn't say impossible."
In addition, Richardson's statement doesn't contemplate the possibility of John McCain being the presumptive Republican nominee. In August, McCain became the first presidential candidate to qualify for federal matching funds in the primaries, and he has indicated he might accept the money.
Should McCain accept public financing and emerge as his party's presumptive nominee, he and Edwards would be in the same boat when it came to fundraising.
The general point that Richardson makes is valid: a candidate's hands are tied by rules governing federal matching money — especially the state-specific spending limits that are based on voting age population instead of political reality. But he overstates the case that Edwards' campaign would be "really" hurt during the important months before the convention.
We find his statement Half True.
