I don't think that Thomas or Squires would have much of a chance. But I'm not sure that Griffin would either. Griffin probably would have very low name ID.

Still searching for a marquee candidate to run for Senate in Georgia, national and state Democrats have asked Gordon Giffin to seek the nomination as the party struggles to stop the Republican political wave that is washing over the South.
Giffin, a former U.S. ambassador to Canada, acknowledged Tuesday that he is considering a campaign and has already spoken with Sen. Jon Corzine (N.J.), chairman of the Democratic Senatorial Campaign Committee.
“The honest truth is, I am giving it some thought,” Giffin said in a telephone interview Tuesday. “I am thinking about it, because of the enormous respect I have for the U.S. Senate.”
