Aponte vote

Take a look at the vote on Mari Carmen Aponte's nomination to be U.S. Ambassador to El Salvador, and you will see the disappearing Republican moderates. They've been voted out (Lugar), scared off (Snowe), and/or backed off past moderation (McCain and Graham). There aren't many more.

It's notable, though, that Marco Rubio voted in favor as he could not afford to alienate his Puerto Rican constituency.
