I've installed a new display at Capitol Hill in Second Life that streams Twitter tweets about candidates.  The tweets float above columns, and are refreshed every minute with a search for Obama, Biden, McCain or Palin. You can also talk to the display to get the latest tweets about an individual candidate. Touch a column, and you get the original post on Twitter that you can use to follow links, etc.

The Capitol Hill region has been one of a number of gathering places in Second Life during the debates. Though a lot of avatars tend to gather at party headquarters, Capitol Hill draws those wanting more of a cross-party discussion.

 As for me, joining the discussion in Second Life, with an eye on the Twitter election channel, and another eye on my TV, makes my head explode.
