McCain-Lieberman?

Senator John McCain (R-AZ)
It may seem outrageous, but it makes political sense. Joe Lieberman recently lost renomination for his senate seat to Ned Lamont, and he has filed to run as an independent. Despite the fact that most major democrats have endorsed Lamont, Lieberman is leading by large amounts in most polls. For the past ten years, he has voted with the democrats,
1. To get Gore's VP pick in 2000 Senator Joe Lieberman (D-CT)
2. To get the Nomination in 2004 (which he didn't)
