Sen. Arlen Specter (R-PA) has changed to Sen. Arlen Specter (D-PA).
*shrug*
He was a moderate on the Republicans' side. Now he's a moderate on the Democrats' side.
Since he now likely to lead an Appropriations subcommittee or two (that he wouldn't have lead as a Republican), his changing parties might move the Senate slightly to the right.
In my opinion, this is less important than whether Al Franken or Norm Coleman become Minnesota's 2008 senator: that election determines whether a new voice enters the Senate.
What do you think?
