Allies of President Trump and Democratic nominee Joe Biden were bullish on Sunday about each candidates’ chances for victory in the presidential election on Tuesday.

Trump campaign adviser Jason Miller predicted Trump would surpass the 270 electoral votes needed to win and reach over 290 on Election Day.

“We believe that we'll be over 290 electoral votes on election night,” Miller said on ABC’s “This Week.” He went on to suggest ballots counted after election night, as mandated by some state laws, would be illegitimate.

“So no matter what they try to do, what kind of hijinks or lawsuits or whatever kind of nonsense they try to pull off, we’re still going to have enough electoral votes to get President Trump re-elected,” Miller said.

Republican Utah gubernatorial nominee Spencer Cox pushed back on Miller’s characterization of the election night count, tweeting “Hey guys, please ignore this type of garbage.”

Ohio Gov. Mike DeWine (R), meanwhile, predicted the president would narrowly win Ohio, a key battleground state Trump won in 2016 that could help determine the winner.

"I think the president wins Ohio,” DeWine said on CNN’s “State of the Union.” “I think it's going to be a close vote. I think he wins by a couple points probably.” Trump won the Buckeye State by just over 8 points in 2016.

On the Democratic side, Pennsylvania Gov. Tom Wolf predicted Biden would carry the pivotal state, which Trump won by under a point in 2016.

“Anything’s possible, but I think Joe Biden’s gonna win,” Wolf said on CNN’s “State of the Union.” “There are a lot of Biden signs all over places that there never were Hillary signs back in 2016. So I think Joe Biden and Kamala Harris are going to do quite well in Pennsylvania.”

Biden campaign adviser Anita Dunn, meanwhile, said the campaign is “not leaving anything to chance” but that the campaign “feel[s] very good about our pathways to victory.”

“We’re campaigning in states that haven’t been competitive in decades,” Dunn told CNN’s Jake Tapper. “We’ve expanded the map and we feel very good about our pathways to victory.”

The comments come as several polls released Sunday showed Biden with slim to wide leads in several battleground states. An ABC News/Washington Post poll showed a dead heat in Florida while Biden leads 51 percent to 44 percent among Pennsylvania likely voters.

In a separate New York Times/Siena College poll, Biden led by three points in Florida, 6 points in Pennsylvania and Arizona and 11 points in Wisconsin.

Biden also led in two national polls released Sunday: an NBC News/Wall Street Journal poll, where he led 52 percent to 42 percent, and a Fox News poll that showed him leading with 52 percent to 44 percent.
