I honestly don't know what to think of the GOP VP picks anymore

Some either hurt one base in terms of voting and help with another (eg. Romney and Huckabee), and others don't really add anything at all electorally or strategically (eg. Jindal, Palin, Sanford, etc.).

Are there ANY candidates that help McCain in any way whatsoever, without alienating part of the GOP base or independents?

Sanford is pretty meh to me, since I can't imagine he would sway any votes.  He doesn't have the inner flare of someone like, say, Mark Warner of Virginia.

Lieberman is a big no no, since I guarantee you social conservatives will turn out in smaller numbers than in '04.  He will definitely help with the Jewish vote, but I think getting a state like PA, which has a significant Jewish base, is a lost cause.  I really doubt that Lieberman, in the end, will be a net positive to McCain, as he runs the risk of lower turnout from conservatives.
