Can I change my early vote in US presidential election 2016? Donald Trump encourages early Clinton voters to switch

Donald Trump suggested that those who voted early for Hillary Clinton should take it back and vote for him as trends showed an increase in interest for changing early votes.

"You can change your vote in six states. So, now that you see that Hillary was a big mistake, change your vote to MAKE AMERICA GREAT AGAIN!" the Republican candidate wrote on Twitter on Wednesday.

Google Trends revealed that there has been a surge in searches for "change early vote" in the U.S. this past week. The states that have shown the most interest include Delaware, Louisiana, South Carolina, Idaho and New Hampshire.

According to CNN, early voters are allowed to change their ballots in states such as Wisconsin, Minnesota, Michigan, Pennsylvania, New York, Connecticut and Mississippi.

In Wisconsin, voters can change their ballots up to three times before it is cast and counted.

"We would let the individual, the voter, vote again and document that this was their second ballot issued. We'd keep a record of that, so they would only have up to three opportunities," Oshkosh City clerk Pam Ubrig told WBAY.

USA Today reported that Pennsylvania does not have early voting but absentee voters can void their previous ballots and vote again if they show up at the polls on election day.

In Michigan, an absentee voter can get a new ballot at the local clerk's office on or before 4 p.m. on Nov. 7.

Early voters will not be able to switch in Florida, North Carolina, Ohio and Arizona.

In the ABC News/Washington Post poll, Clinton is ahead by 13 points at 54 to 41 among early voters but Trump leads 41 to 39 among those who are planning to vote on election day.

The poll indicated that 21 percent of the respondents have already voted while 24 percent have said they are planning to vote early. Around 24.7 million early votes have already been tracked by the United States Election Project.
