The Democratic Senatorial Campaign Committee is finding ever-creative ways to attract donations from supporters.

The latest is an email letter from James Carville, asking for $1.2 million in donations from backers to stem Karl Rove's American Crossroads ads attacking Democratic candidates.

The letter reads:

"Dear Karl,

"I saw you poured $1.2 million into mudslinging TV ads in five battleground states. Bad news, though: My side’s grassroots supporters just matched you, dollar for dollar. So if you thought you were gonna buy yourself the White House and Senate with all that money, tough biscuits.

"Sorry about you wasting all that cash. Maybe just go to Vegas next time? Love,
James"

The email asks supporters to make the donations by May 1, and the money would be matched by Democratic Senators. It goes on to say:

"How much fun would it be if, in between opening up those big checks from his Big Oil and Wall Street pals, Karl got that note? More importantly, how huge would it be if folks like you matched his ad buy and stopped him from taking the four seats Republicans need to run the Senate?

"After all, Rove and his pals aren’t spending all this money just to get the frequent flier miles. They’re trying to buy the White House and the Senate so they can end Medicare as we know it, turn back the clock on women’s rights, and throw the middle class under the bus.

"Their agenda stinks – but your grassroots support can fight it. And if you can match Karl’s ad buy, we can neutralize the special interests and protect President Obama and our majority."
