A Des Moines woman has been charged with Election Misconduct, a Class D felony, after allegedly voting twice for GOP presidential nominee Donald Trump. Terri Rote says she was afraid her first ballot for Trump would be changed to a vote for Democratic candidate Hillary Clinton.

"I wasn't planning on doing it twice, it was a spur of the moment," says Rote.* "The polls are rigged."

But Polk County Attorney John Sarcone says voter fraud in Iowa is very rare, which is evidence that Iowa’s election system is secure.

"I think in the 25-plus years that I've been doing this job, this maybe the third [time] we've had some irregularity that's resulted in a criminal charge," says Sarcone. "People aren’t voting more than once. And if they do, or attempt to do it, they will get caught because there are safeguards in place....We want everybody to exercise their right to vote, but only once."

Rote was released from jail on Friday on a $5,000 bond. If convicted, she faces up to five years in prison.
