President-elect Donald Trump might not have won the popular vote, but he would have if he had needed to, conservative talk radio host Rush Limbaugh said.

Supporters of Democrat Hillary Clinton have been touting the fact she won the popular vote, suggesting Trump does not have a full mandate to pursue his agenda. But Limbaugh said on his show Monday that Trump didn't focus on winning the popular vote since that is not how the race is decided.

For that matter, neither did Clinton, he said.

If the Electoral College didn't exist, "It would have made states like New York and California automatically in play," Limbaugh said. "They're not now. Trump didn't spend any time in California, very little time in New York because there was no point."

Even if every Republican in both states voted for the GOP nominee, there still would be no chance of it going red, Limbaugh said.

"But what if there was no Electoral College?" he said. "You wouldn't have had nearly as much time spent in North Carolina. You wouldn't have had nearly as much time spent in Wisconsin by Trump or Michigan or Ohio or some of these Rust Belt states. You would have Trump going where the people were. He would have gone to New York. He would have gone to California. He may not have needed to win the state, but if the popular vote were all that counted, he could have easily won this election by simply changing focus."

That said, Limbaugh said he expects Trump will end up winning this year's popular vote anyway once all votes are finally counted.

He said he believes a "significant number" of illegal immigrants voted.

"I wouldn't be surprised if the number is as high as two million illegal immigrants."
