PORKBUSTERS UPDATE: Here’s an interesting report:

Senators Frist, McConnell, and Sessions just finished assembling over 34 Senate signatures on a letter backing the veto threat the President laid out yesterday on the groaning Senate supplemental. This plan—have the President say he will veto a fat bill, and have the Senate leadership deliver fiscal conservatives to that cause—should serve as a rallying point for those who have been horrified at the spending spree underway in Congress, for which the House, Senate, and White House all share responsibility. It’s time to rally to the fiscal conservative flag, and the sooner our friends in the conservative community know that there is a majority in the Senate worth listening too when it comes to spending matters, the sooner people can realize what the stakes really are in November.

I think that this should be a bipartisan issue — but it’s certainly true that Republicans have the most at stake in getting this under control at the moment, since they’re in charge.
