Protip on corporate welfare: it costs money to buy a filibuster.

Think Progress reports on the terrific success that oil companies had last night with their purchased GOP senators:

[Last night the Senate majority tried] to repeal $21 billion in subsidies for the big five oil companies — the same companies that made over $30 billion in profits in just the first three months of 2011.

[...] An analysis of campaign contribution records shows the gusher of dirty cash that fueled the filibuster:

A Center for American Progress Action Fund analysis finds that the 48 senators who sided with Big Oil received over $21 million in career oil contributions, while 52 senators who sided with the American people received only $5.4 million in contributions. Each senator who voted for Big Oil received on average more than four times as much oil cash as those who voted to end the subsidies.

While eight Republican senators voted for a bill that included a repeal of tax breaks for big oil in 2007, only Sens. Susan Collins and Olympia Snowe of Maine voted with the Democrats in supporting ending taxpayer handouts to big oil tonight. Sen. Mary Landrieu (D-LA), Mark Begich (D-AK), and Ben Nelson (D-NE) joined the Republicans to protect the oil companies’ corporate welfare.
