A John McCain/Joe Lieberman Ticket?

There's been a lot of speculation on the internet about the possibility
of John McCain picking Joe Lieberman as his running mate. Then I
just finished seeing this Google Ad paid for by the John McCain campaign:



Interesting how it says "join our team." It might be an attempt to
appeal to disaffected Democrats after such a hard fought primary.
I just thought I would post it and let speculation run wild!

Update: I found the ad again and it leads to this page. So that
explains it. The ad is intended to reach Democrats and Independents.
