While Mitt Romney was at Bain Capital, almost one out of every four companies they were involved with went bankrupt or went out of business.

Here's the biggest problem I think Donald Trump has. He's not getting enough votes today of the people who already say they don't like Hillary Clinton.

Pennsylvania might be a parochial state, but it's not a homogeneous state. So, even among just Republican voters, to be able to pull that off, when you have very moderate voters on one side of the state and more conservative in the middle, shows that Donald Trump has very, very broad support.

People are looking for something sort of new and exciting to be part of. It`s like test-driving a car. You don`t want to just go on the lot and drive the car you had before, you want to drive something new.

What they're still unsure about, particularly some moderate Republicans, we know gender there is difference, I think Donald Trump has to seal the deal by letting people feel comfortable to vote for him.

To some extent it [Mr. Bush's standing in the polls] is affecting the races, but only because the races really haven't begun. At some point these races are going to be about the two candidates in each race. This is ultimately not going to be about Bush helping or hurting someone getting elected, but ultimately will be about the candidates' records.

[People] feel Washington doesn't understand their lives anymore, and they feel that even though Donald Trump might make a mistake with what he says from time to time, they see that as authenticity and maybe somebody who will truly pay attention to them, because they feel ignored.
