Pollsters linked to the Clinton and Trump campaigns have started wondering if there is a secret Donald Trump vote and now a new survey of voters shows that the vote exists, especially among Republicans who are reluctant to tell the truth.

Rasmussen Reports on Wednesday provided results that could indicate that its daily horse race poll, which shows Hillary Rodham Clinton and Trump virtually tied, undercounts the Republican's support.

The survey analysis said that in its latest telephone survey, "17 percent of 'likely Republican voters' are less likely this year to let others know how they intend to vote compared to previous presidential campaigns."

What's more 10 percent of Democrats aren't telling the truth to pollsters.

And 25 percent of voters not affiliated with either party, a group that has been trending for Trump, "say they are less likely this year to say publicly which presidential candidate they will vote," said Rasmussen.
