A new poll shows that Donald Trump has company as the Republican presidential front-runner.

According to a survey of likely Republican voters from Monmouth University, Ben Carson is tied with Trump in Iowa.

The poll has Trump and Carson leading the way with 23 percent each, followed by Carly Fiorina with ten percent, Ted Cruz with nine percent and Scott Walker with seven percent.

In addition, a new Quinnipiac University poll found that 71 percent of American voters are dissatisfied with the way things are going in the country.

Larry Sabato said on "Your World" that it's unusual to see three GOP candidates - let alone Washington "outsiders" - taking up 56 percent of the vote.

He said that Carson's meteoric rise can be attributed both to voters' frustration with Washington politics and the long campaign trail, which has given people exposure to Carson over many months.

"Because of that, candidates who don't have a lot of money to spend or who aren't melodramatic - and that certainly describes Ben Carson - have an opportunity to be heard," Sabato explained. "People gradually get to know them, they learn about them, and they may be impressed by them."

"And that's what's happened here with Ben Carson."
