President Trump on Tuesday urged Americans who have already cast their ballot to change their vote for him after the term began trending on Google. 

"Strongly Trending (Google) since immediately after the second debate is CAN I CHANGE MY VOTE? This refers changing it to me. The answer in most states is YES. Go do it," the president said on Twitter. "Most important Election of your life!" 

The term "change my vote" registered a strong uptick on Google Trends on Oct. 24, the week after The Post published its exposé series about former Vice President Joe Biden's alleged involvement in Hunter Biden's business dealings in Ukraine and China, and continued climbing during the time of the final presidential debate between Trump and Joe Biden last week. 

The Google searches for "change my vote" had the most interest in Arizona, Florida, Idaho, Minnesota and Pennsylvania. 

People who searched "change my vote" also searched for "Hunter Biden" and Hunter Biden-related queries, according to Google. 

An estimated 65 million people have already cast their ballots before the Nov. 3 election. 

Some states allow voters who have changed their minds to submit a new ballot, Matthew Weil, director of the Election Project at the Bipartisan Policy Center, told Newsy. 

That includes New York, at least for those who mailed in an absentee ballot. 

"The Election Law recognizes that plans change," the state Board of Elections says. 

"Even if you request or cast and return an absentee ballot, you may still go to the polls and vote in person," the rules state. 

In Arizona, Florida, Idaho and Minnesota, residents who voted by mail can vote with a provisional ballot on Election Day. Election officials urge voters to bring ballots not sent in the mail with them to the polling place. 

In Pennsylvania, voters can bring their mail-in or absentee ballot with them to the poll to be voided or sign a declaration to be able to vote on Nov. 3. 

In Michigan, absentee voters can request that local election officials invalidate or "spoil" their first ballot and submit a new one until 5 pm on the Friday before Election Day or in-person until Monday at 10 am the day before Election Day. 

Wisconsin absentee voters can "spoil" their ballot and request a new one or vote in-person before certain deadlines, according to a 2020 memo memo put out by the Wisconsin Elections Commission. 

In New York, voters can cast a new ballot in-person either early or on Election Day and ask that their initial ballot be invalidated. 

Casting new ballots in permitted in some Connecticut towns, but it varies across the state. 

In New Hampshire, voters can request a new ballot if election officials determine there's enough time to do so, and they can vote in-person on Election Day if the initial ballot was not yet counted. 

In several other states, including Pennsylvania, Illinois, Delaware, New Mexico, Idaho, Indiana, Arkansas, and Mississippi, voters are allowed to "spoil" a ballot and request another, but only if the initial ballot hasn't yet been returned or, in some cases, processed. 

The deadline to invalidate a ballot and request another has already passed in Minnesota.
