Greg Sargent at TPM Cafe asked the Lieberman campaign whether he would rule out running on the Republican line in November. Amazingly, Joe's spokesman refused to answer:

Will Lieberman or will he not rule out running on the GOP line if he loses to Lamont in August and it's offered to him?

This is fairly straightforward: Yes, or no? Which is it?

The question has been posed to Lieberman campaign deputy press secretary Noah Kores, and the campaign is mulling it.

Election Central will let you know when -- or if -- we get an answer. Don't touch that dial.

This is the same evasion that Lieberman pulled in the run-up to his July 3rd announcement that he was going to run as an Independent.

Update: Commenter "blogswarm" at MyDD puts it succinctly:

If you are Deputy Press Secretary (Noah Kores) and somebody asks if you'll run as a Republican, you should be fired if you don't immediately answer, "HELL NO!"

If you are "mulling" it over because the candidate would actually consider running as a Republican after losing the Democratic Primary then the candidate needs to be fired.
