Here's the latest on which Democratic contenders are taking public financing for their campaigns.

Those that accept public financing are limited in what they can spend. Those that forego it, like Bush in 2000, can spend whatever they want.

Bush spent $100 million in 2002. "With an increase in contribution limits under the nation's new campaign finance law, some of Bush's fund-raisers think he can raise $200 million or more for the primaries, money he could spend through the spring and summer to take on the presumptive Democratic nominee."

"The presidential campaign fund is financed by taxpayers with a $3 checkoff on their tax returns. In 2000, those who accepted public financing, including then-Vice President Al Gore, were entitled to up to $16.9 million in matching funds. In exchange, they had to abide by spending limits; Gore could only spend $40.5 million in the Democratic primaries, for example."

Howard Dean, Al Sharpton, former Illinois Sen. Carol Moseley Braun and Ohio Rep. Dennis Kucinich are taking public financing. Kerry is up in the air. Edwards most likely will take it. Graham hasn't gotten around to thinking about it yet, he's still assembling a campaign team.
