A majority of Republican voters -- and nearly six in 10 GOP Tea Party supporters -- say they aren't concerned about the sexual-harassment allegations directed at Republican presidential candidate Herman Cain, according to a new NBC News/Wall Street Journal poll.
But his standing among all respondents has declined since these allegations first surfaced last week.
In the poll, 54 percent of Republican voters say they aren't concerned about voting for Cain after these allegations, while another 15 percent say they are "just a little" concerned.
By comparison, only a combined 13 percent of Republicans say they are a "great deal" or "quite a bit" concerned about voting for Cain.
But among all adults, negative opinions about Cain have increased in the past month.
In October's NBC/WSJ survey, 24 percent of all respondents had a positive impression of the ex-Godfather's Pizza CEO, and 18 percent had a negative impression of him.
But according to this new poll, that negative number has jumped up to 35 percent, while 23 percent have a positive opinion of Cain.
The NBC/WSJ poll -- which was conducted Nov. 2-5 of 1,000 adults, and which has an overall margin of error of plus-minus 3.1 percentage points among all respondents (and 6.2 percentage points among GOP primary voters) -- will be released in full beginning at 6:30 pm ET.
