After President Donald Trump on Thursday made allegations of widespread voter fraud in the presidential election system, we’re taking a look at the facts.

“This is a case where they’re trying to steal an election. They’re trying to rig an election,” Trump said.

Orange County Republican Party Chairman Charles Hart says that when Trump makes remarks like that, he’s just saying what Republican voters are already thinking.

He says Trump voters are suspicious when they see early leads for Trump in some states get overtaken by mail-in ballots being counted later.

“When you have this situation with votes just magically appearing, I mean it does cause some concern. And certainly a lot of people do ask questions about it, and I think rightfully so,” Hart said.

While waiting for states to tally up the final numbers of votes in key states for the presidential race is frustrating for many, these delays were expected.

Since Election Day, Trump has taken to Twitter alleging voter fraud. However, University of Central Florida political science professor Aubrey Jewett explains it is not fraud, just different state laws.

Jewett says laws in some states, such as Pennsylvania, make their count much less efficient than in Florida.

“It’s not fraud or delay. It’s just the fact that their rules allow ballots to be counted as long as they’re postmarked by Election Day, and so that slows them down,” Jewett said.

He says this was anticipated because some states cannot count mail-in ballots until Election Day and some allow mail-in ballots to be counted so long as they are postmarked by Election Day, so those final tallies take time.

“I mean there are legitimate questions in some cases, again that's perfectly fine. But it’s a little bit different than making broad unsubstantiated statements that entire states or entire methods of voting are just filled with fraud when there is very little evidence to support those claims,” he explained.

Jewett, who has studied elections for decades now, says with the vote in some key states so close, it is normal for campaigns to file lawsuits like the Trump campaign did, saying the Democrats would have done the same thing.

“I certainly don’t begrudge President Trump and his team from filing lawsuits in states where the vote is so close. Democrats would’ve done the exact same thing,” Jewett said.

However, what is not normal, Jewett says, is making broad, unsubstantiated claims of voter fraud nationwide.

Jewett says while small acts of election fraud are possible, he stresses it would be incredibly difficult to pull off widespread voter fraud in this day and age.

“It’s a little bit different than making broad, unsubstantiated statements that entire states or entire methods of voting are just filled with fraud, when there is very little evidence to support those claims,” Jewett said.

He says he knows it would be incredibly difficult to pull off the kind of election rigging that Trump is alleging.

“Small acts of fraud are certainly possible, but widespread acts that would have a big impact on the results in a race are very difficult, and, in fact, are almost nonexistent in the literature and in the history or investigative journalism and political scientists who have looked at these things," Jewett said.

He adds that, even with mail-in ballots, there are multiple safeguards to make sure ballots are valid and counted.
