Twenty percent of Republicans and Republican leaning-independents in the latest ABC News/Washington Post poll say they’d be less likely to support a candidate who’s a Mormon; that compares to 36 percent when Romney entered the national political stage in December 2006.

Far more, 54 percent, say they’d be less apt to support a candidate for president who’s been unfaithful to his or her spouse. And 50 percent would be less apt to support a candidate who favors civil unions for gay couples.

Two other items are positives overall, if somewhat divisive. Forty-five percent of leaned Republicans say they’d be more likely to support someone who favors major changes in Medicare, but 21 percent would be less apt to support such a candidate. Thirty-one percent say they’d be more likely to back a candidate who’s supported by the Tea Party political movement; 14 percent, less so.
