Dems beside themselves on Frist visit to SD

The WaPo has a few paragraphs on Senate Majority Leader Bill Frist's plans to come to South Dakota to campaign for Thune. The Dems are really working the "tradition" angle to pressure Frist not to come to South Dakota. But wasn't it a "tradition" not to filibuster judicial nominees too? Daschle certainly didn't hesitate to break that tradition when it suited him.
