Steve Cortes, a senior advisor on President Trump’s reelection campaign, said Sunday he expects a “similar scenario” to the 2016 election, where Trump may head into Election Day lagging behind his Democratic opponent and still pulling out a win. 

Cortes was dismissive of indicators of Democratic presidential nominee Joe Biden’s lead in the race, including data that more Democrats are requesting mail-in ballots ahead of the election. 

“In key swing states, Florida and North Carolina and Pennsylvania, Democrats lead Republicans by hundreds of thousands of requests for mail ballots in two of those three states by more than 2:1,” Chris Wallace, host of “Fox News Sunday” said.

“Between the president talking down mail and voting, Steve, and the fact that you've gone largely dark in a lot of these states in terms of TV ads, aren’t you just buying the Democrats a big early lead?” Wallace asked. 

“Well, I don’t think so,” Cortes responded, adding that the campaign is doing  “a heck of a lot of digital advertising in those states.”

“But what I would say regarding mail-in is look, in 2016, we were losing the race until Election Day and then won it big on Election Day, at least big electorally. And I have the same view this time around,” he continued. 

Cortes also said that “we don’t know for certain” that all Democrats requesting ballots are voting for Biden. 

“But regardless, I would concede that it’s probably going to be a similar scenario, where -- when we look back retrospectively, we will probably see that the president was down into election day and then won election day itself by an incredibly wide margin. And I say that, by the way, largely because of the enthusiasm gap which is very real between our supporters and Joe Biden’s,” Cortes said. 

Recent polls have shown Biden leading Trump nationally as well as in a number of key battleground states. A Fox News poll released Sunday found Biden with a 5-point lead over Trump nationally, and a separate CBS News poll released Sunday found Biden with a slim lead in Arizona and a larger lead in Minnesota. 

Months out from the 2016 election, though, many polls indicated then-candidate Trump was trailing Democratic nominee Hillary Clinton in the election that resulted in his victory.
