Style guide for the media:
If you are writing about Joe Lieberman's activities in the US Senate it is fair to refer to label him as Senator Joe Lieberman (D-CT).
However, if you are writing about his election campaign you should label him according to the party he has formed and joined, the Connecticut for Lieberman party.
CNN.Com says he has enough signatures to be on the ballot. So, (CFL-CT) it is.
