ABC News and Yahoo are streaming live interviews with each of the major Republican presidential candidates today, but none of them have been very willing to entertain questions about the scandal.

Jon Huntsman: It’s a distraction and Herman Cain can deal with it however Herman Cain chooses to deal with it... Far be it from me to advise Herman Cain

Michele Bachmann: I don’t have any information about these allegations whatsoever. I have absolutely nothing to contribute to that discussion.

Mitt Romney: These are serious allegations and they’re going to have to be addressed seriously.

Among political activists, however, there is evidence of a shift in sentiment toward Cain. Jennifer Jacobs of the Des Moines Register interviewed several Iowa conservative leaders after Sharon Bialek came forward Monday with her account of an inappropriate incident with Cain.

Bob Vander Plaats, one of the most prominent evangelical leaders in Iowa, called the incident “a tipping point for the viability of his campaign,” though some Republican pundits remain skeptical of the allegations, as the Fix’s Rachel Weiner reported Monday.

Cain has denied the charges and today his campaign questioned the motives of Bialek and her attorney Gloria Allred.

Cain has signaled no intention to stall his activities on the campaign trail in response to the allegations. He told comedian Jimmy Kimmel in an interview Monday he is taking the issue “head-on.”
