A growing number of American voters do not believe Joe Biden legitimately won the 2020 presidential election, with less than half of respondents in a new poll stating they are certain of Biden's victory. The findings suggest a lasting impact from Donald Trump's persistent claims that the election was fraudulent.

According to a July survey conducted by Daily Mail/JL Partners, only 48 percent of American voters affirmed that Biden definitively won the 2020 election. The poll indicated that 34 percent of respondents believe Trump won, while 18 percent remained unsure.

No evidence of widespread fraud in the 2020 election has ever been substantiated. Biden secured victory with 306 electoral votes to Trump's 232, winning by more than seven million popular votes. These results were certified by every state and have been upheld in numerous court challenges.

The poll highlighted a stark partisan divide, with approximately 70 percent of Republicans falsely believing Trump won the 2020 election. Only 15 percent of Republicans acknowledged Biden's victory. Conversely, 80 percent of Democrats stated that Biden won, although 10 percent of self-identified liberals also claimed Trump was the victor.

Trump has consistently maintained, without providing evidence, that he won the 2020 election. Allies of the former president have largely defended this assertion.

In a recent public statement, Trump claimed that China had interfered in the 2020 election and that there were nearly 275,000 noncitizens on U.S. voter rolls. While Trump suggested Chinese interference, he did not explicitly state that it altered the election's outcome, nor did he announce any specific consequences.

Some Republican figures have expressed skepticism regarding these claims. Alaska GOP Senator Lisa Murkowski commented after Trump's address, stating that such assertions had not swayed her opinion. Ben Ginsberg, a Republican attorney who previously worked on presidential campaigns, noted the continued absence of documented evidence to support claims of incorrect election results.

One Republican House member told the Daily Mail that obtaining voter data does not equate to election theft, adding that such data is commercially available. This individual emphasized that Trump's speech did not present evidence of interference that would have changed the election's outcome.

White House spokeswoman Abigail Jackson stated that President Trump is committed to ensuring accurate elections and up-to-date voter rolls, free from errors and unlawfully registered non-citizen voters. She added that this commitment is why Americans re-elected him.

A January 2024 poll by The Washington Post and the University of Maryland found that 62 percent of adults believed Biden's 2020 win was legitimate, a decrease from 69 percent in December 2021. The Daily Mail/JL Partners survey indicates a continuation of this trend.

Many Republican lawmakers initially supported Trump's claims of a stolen election in 2020. However, following the January 6 U.S. Capitol riot, several shifted their stance.
