Donald Trump's mantra of a rigged election is sinking in with voters, 41 percent of whom believe it could be "stolen" from the GOP nominee due to voter fraud, according to the latest Politico/Morning Consult poll released Monday.

The results:

73 percent of Republicans think the election could be stolen from Trump;

17 percent of Democrats think the election is prone to fraud;

30 of registered voters are not confident votes will be counted accurately.

"The results show that voters are increasingly losing confidence that votes around the country will be counted accurately on Election Day," said Kyle Dropp, cofounder and chief research officer at Morning Consult.

Trump has banged the drum on a rigged election more heavily the past two weeks as his drop in national polls has coincided with the damning audiotape of his lewd comments about women and then several allegations of groping.

Yet, 60 percent — 70 percent of Republicans — of those surveyed think it's necessary to raise questions about accuracy of election results, Politico reported in its poll.

This poll was conducted from Oct. 13-15 among a national sample of 1737 Likely Voters. Results from the full survey have a margin of error of plus or minus 2 percentage points.
