Certainly, new polling data from Reuters/Ipsos would seem to support that thesis.  A new poll of 1,192 Americans, conducted by Reuters, found that if Hillary wins only 50% of republicans would accept her presidency as legitimate while 70% would attribute her victory to voter fraud and/or vote rigging of some type.  Moreover, only 20% of republicans surveyed felt that the final vote tallies would be accurate.

Only half of Republicans would accept Clinton, the Democratic nominee, as their president. And if she wins, nearly 70 percent said it would be because of illegal voting or vote rigging, according to a Reuters/Ipsos poll released on Friday.

 Conversely, seven out of 10 Democrats said they would accept a Trump victory and less than 50 percent would attribute it to illegal voting or vote rigging, the poll showed.

For example, nearly eight out of 10 Republicans are concerned about the accuracy of the final vote count. And though generally they believe they will be able to cast their ballot, only six out of 10 are confident their vote will be counted accurately.
