President Donald Trump formally announced his re-election bid this week in Orlando, Florida–and just days into the campaign, his campaign manager Brad Parscale says he thinks Trump will win in an “electoral landslide” in 2020.

According to Fox News, Parscale said the president will win Florida again–where he won a slim victory in 2016 against rival Hillary Clinton.

“I think [he’ll have] even more electoral points than he did last time,” Parscale told CBS News.

Back in 2016, Trump defied the polls by beating Clinton in Wisconsin, Michigan, and Pennsylvania–all by very slim margins. He won the election with 306 electoral votes, even though Clinton won the popular vote nationwide.

Despite Parscale’s optimism, polls have shown that Trump may have a relatively uphill battle in 2020. A recent Fox News poll found that former Vice President Joe Biden holds a wide lead in the Democratic field, and even has a 10-point lead in a hypothetical head-to-head matchup with President Trump.

When Parscale was asked about the polls, he argued that poll are not reliable because they do not reflect enthusiasm or voter turnout. He said, “The country is too complex now just to call up a couple hundred people and ask what they think. … The way turnout now works, the ability we have to turn out voters, the polling can’t understand that.”

Parscale ran Donald Trump’s digital platforms and social media in 2016; he said the president’s use of social media is one key reason his supporters are very enthusiastic about the president. While many presidential candidates only use online platforms to make official announcements and statements, the president has been more candid online; this allows him to have a natural and unfiltered conversation with his own supporters without any media bias altering his message.

As the 2020 election nears, it is still unclear who Trump will be up against in the general election. The first Democratic Primary debates are fast approaching, and will likely play a key role in who the Democrats choose as their nominee. While the energy on the left certainly seems to be around the more progressive candidates such as Bernie Sanders and Elizabeth Warren, polls suggest that Joe Biden would have the best chance at beating Trump in a general election.

However, with still more than a year to go until the big election day, it is truly anybody’s guess as to who will ultimately come out on top. As we learned in 2016, polls are often not a good indicator of reality.
