The Republican incumbent has regularly trailed Democratic Party nominee Joe Biden by a significant margin in most recent national polls.

The average compiled by FiveThirtyEight has Biden ahead by just over nine percentage points, with about 52 percent backing the Democratic nominee and 43 percent supporting the president.

The trend is mirrored by the RealClearPolitics average, which gives Biden 51 percent of votes to Trump’s 43 percent.

In California, the picture is even gloomier for the president. According to FiveThirtyEight’s average of presidential election polls, Biden is on track to secure 62 percent of votes in California, with Trump currently polling 26 points behind at 36 percent.

Huff, however, believes the president should pay little attention to polls and projections.

“If it’s a fair election no way @realDonaldTrump loses California,” the two-time World Series champion tweeted on Sunday night.

“The amount of boat parades, rallies, & pro Trump signs I’ve seen is off the charts. “Mark my words California is flipping red this year! #Trump2020”

Huff has long been an outspoken Trump supporter and in November last year he posted a picture on Twitter of him holding a shooting target with holes, suggesting he was teaching his boys how to use a gun in the “unlikely event” Bernie Sanders defeated Trump in the presidential elections—Sanders eventually withdrew from the Democratic Party primaries in April, before endorsing Biden.

Trump himself launched a last-minute plea to swing voters in the Golden State last week, tweeting that: “California is going to hell. Vote Trump”

The most populous U.S. state, California holds a total of 55 electoral votes—the most of any states—and has backed the winner 32 times in 42 presidential elections.

A Republican stronghold for three decades from the 1950s—aside from Lyndon Johnson in 1964, no Democratic candidate won the state between 1948 and 1992—California has turned into a safe bet for the Democrats over the past 30 years.

George H.W. Bush remains the last Republican to win the state in the race for the White House, receiving 51.1 percent of votes in 1988. In each of the seven presidential elections held in the intervening 32 years, the state has voted for the Democratic candidates who on average have received 55.4 percent of votes.

In the last three presidential election, support for the Democratic Party in California has grown even bigger. Barack Obama took the state with 61 percent of votes in 2008 and 60.2 percent as he won a second term four years later, while in 2016 Hillary Clinton won 61.7 percent of votes compared to Trump’s 31.6 percent.

According to official figures, California has sent mail-in ballots to approximately 22 million registered voters and over six million of Californians had returned their vote by October 22.

“We’ve been tracking this kind of stuff for over a decade, and there’s just nothing that compares to how quickly voters have been returning their ballots this election cycle,” Paul Mitchell of California-based bipartisan voter data firm Political Data Inc told The Guardian at the weekend.
