Polling expert warns against overestimating polls: In the past two elections, they underestimated Trump.

Nate Silver, a polling and data expert, stated on Wednesday that Vice President Kamala Harris has a slight edge in winning the presidential election if it were held today, but warned the public not to rely heavily on polls due to their history of being incorrect when predicting the outcomes of elections involving former President Trump.

"Silver stated on "Special Report" that if the election is tomorrow, he believes Harris would be a slight favorite. According to Silver, Harris has been ahead in recent polling in the "blue wall" states, including Pennsylvania, Wisconsin, Michigan, Georgia, North Carolina, Arizona, and Nevada, all of which are within the margin of error range."

"He emphasized the importance of remembering two things: firstly, there are three more months left, and secondly, the polls have been incorrect before, particularly in the last two general elections where they underestimated Trump."

Earlier Wednesday, a prominent elections analyst and statistician released a polling update on his Substack forecast page, indicating a series of "strong swing state" polling for Harris.

The race is still in a toss-up range, but Harris's momentum has been consistently upward, according to him.

"In America's polarized political climate, most elections are close, and a candidate is rarely out of the running," he added. "Needless to say, stranger things have happened than a candidate who was behind in the polls winning."

After initially predicting that former President Trump was electorally favored to win the White House in November, Silver recently changed his election prediction to "toss-up," with Harris winning the popular vote.

In his updated prediction on Substack in early August, Silver stated that when he launched the presidential model on June 26, he believed that the election was not a toss-up. Instead, he predicted that Joe Biden was consistently behind in the states that were most likely to decide the Electoral College, making him a 2:1 underdog in the election despite the uncertainties in the race. However, Silver noted that Biden's situation was not irrecoverable until the debate. He added that he would rather have had Donald Trump's hand to play every day of the week and twice on Sundays.

"With the election now in Kamala mode, it's unclear which position you'd prefer, and I wouldn't blame you if you wanted to bet on either Harris or Trump," he said.

Silver explained to Baier on "Special Report" that his polling relies on models, emphasizing that "models are not always accurate."

Our view is that the polling bias is unpredictable and can go in either direction. If Pennsylvania is Harris plus 2 on Election Day, it could be Trump wins by 2 or Harris wins by 6, et cetera.

The author of the new book "On The Edge," Silver, predicted that the Harris campaign will have a strong finish in August, thanks to the Democratic National Convention next week. He stated that Trump has been "knocked off his campaign a little bit" after Biden withdrew from the race, with Harris taking his place.

"Silver contended that the Democrats were unprepared for a change in the presidential candidate and made tactical errors, such as focusing on the candidate's race rather than issues like immigration and the economy."

September marks the beginning of a new month, and with it comes at least one debate, possibly even multiple debates. Harris will have higher expectations than she currently holds.

On Wednesday, Planet Chronicle published a national survey showing Trump leading Harris by one percentage point, 49-50%. According to the same survey, more Democrats support Harris (94%) than Republicans back Trump (93%), while Independents go for him by 8 points.

In the poll, an equal number of voters preferring Harris and Trump are highly motivated to vote this year (68% each). Last month, Trump supporters (66%) were 5 points more motivated than Biden supporters (61%) to vote.

Voters prioritize the economy, with 38% stating it will be the most crucial issue in their presidential vote. Immigration and abortion follow closely, both at 14%, while all other issues are tested in single digits.

Silver said the new poll is "pretty good" news for Trump.

He added that it would assist a bit when they updated their model tomorrow.
