Roughly half of voters who said they voted for Donald Trump last November, 49 percent, believe Trump won the popular vote, according to a new POLITICO/Morning Consult poll. That's compared to 40 percent who say Democrat Hillary Clinton won.

Overall, a majority of voters, 59 percent, believe Clinton won more votes than Trump, but 28 percent believe Trump won more votes.

Respondents were asked which presidential candidate won the national popular vote and the Electoral College after Kansas Secretary of State Kris Kobach — the vice chair of Trump’s controversial Presidential Advisory Commission on Electoral Integrity — said in a televised interview last week that "we may never know" whether Clinton won the popular vote.
