Final Four Update: So a combination of Porkbusters and Muckraker tallies has the search for the "secret hold" Senator down to the Final Four. Is it Sen. Mike Crapo (R-Idaho), Sen. Orrin Hatch (R-Utah), Sen. Judd Gregg (R-N.H.), or Sen. Ted Stevens (R-Alaska)? The money is pick is Stevens who's had it out for Coburn ever since the Oklahoma Senator killed the "Bridge to Nowhere". (Frist calls on all Senators to "honestly and transparently" answer whether they are the "secret Senator" when contacted by "the blog community".)
