The earmark-mania is not unique to either party -- both Democrats and Republicans contributed to what Taxpayers for Common Sense estimates is 8,570 disclosed earmarks worth $7.7 billion in the bill that would fund the government through the end of the fiscal year.
But the Republican crossovers in particular have a lot at stake in the package.
Two of the three Republicans on Senate Majority Leader Harry Reid's "definite" list have authored 129 total earmarks worth $190 million, according to an updated list from Taxpayers for Common Sense.
Sen. Richard Shelby, R-Ala., is actually the second-biggest earmarker, according to the list, with 64 earmarks worth $114 million. Sen. Thad Cochran, R-Miss., is a few notches down, with 65 earmarks worth $76 million.
Both are expected to support the omnibus bill -- along with Maine Sen. Olympia Snowe, who has zero earmarks.
