Jeb Bush blasted Donald Trump by comparing him to President Obama on Tuesday.

At a campaign stop in Council Bluffs, Iowa the former Florida governor said that Trump's rhetoric on immigration is as divisive as President Obama's comments on class warfare.

“On our side there are people that prey on people’s fears and their angst as well. I don’t know about you, but I think it is wrong. I believe we need to unify our country. We need to stop tearing — separating ourselves by race and ethnicity and income. We need to focus on the things that tie us together, and whether it’s Donald Trump or Barack Obama, their rhetoric of divisiveness is wrong,” Bush said.

He also emphasized the need for Republicans to have a positive message exemplifying why conservative values will benefit all Americans.

“A Republican will never win by striking fear in people’s hearts. A Republican can win, and will win, if we have an aspirational message that gives people hope that their lives will be better when we apply conservative principles the right way,” he continued to a round of applause.

Bush, who was previously leading in all polls, announced on Fox News Sunday that he was done discussing Trump, but apparently seeing the billionaire's ascendancy has changed his mind.
