Fair point so I'll rephrase to say that she won't trash any serious candidate by name.
If she trashes Sarah Palin and Sarah Palin doesn't run, then Bachmann just lost the only person who could give her enough support to beat Romney.
Frankly I think it is Bachmann who is not the serious candidate. She is a candidate for Romney's VP slot. That is why she won't mention him by name.
If Palin doesn't run, she will most likely lend all her support to Perry. Bachmann may have burned the bridge to nowhere and she is stuck on the wrong side.
ROFLOL, now that was a good zinger.
