This Republican race for months and I'd say for months to come is still marked by fluid electorate.

Republicans were more willing to work with Barack Obama than Democrats were.

This Republican race for months to come is still marked by fluid electorate.

It tells me that if he really wants to do well and run for presidency, he needs to up his game and focus more on the issue that counts, which is the economy.

It is a strong move by Governor Perry and here's why. What you're seeing on the Republican side from Governor Perry, from Herman Cain and to a lesser degree from Mitt Romney is a desire to fundamentally change how Washington is doing its…

The purpose of the tax code should be to raise the revenue so the government can pay its bills.

What you're hearing in this year's debate is that Republicans are really the party of fundamental change and President Obama is the one who really is defending the status quo that brought us the current economy and the current tax mess…

Those are their words. And that's what -- this ad certainly is not conventional.

But what this ad does reinforce is that he will stand up to political correctness. And that does resonate in Republican circles.

I think we're down to three. And I still think the race for who is the anti-Romney is an important race in case something goes wrong with Romney and he loses. Whoever is left standing has a chance.

The Occupy Wall Street movement is going to get big, very big.

Our Constitution says there is no religious test for the presidency or for any other high office or low office of this country. That's the spirit on which our country was founded.

There's still the anti-Romney element out there in the Republican Party.

If you're going to become, as Mary says, a serious presidential contender, you have to go beyond the lines of make a crowd whoop and cheer and you have to be presidential.

This is a year where people are fed up with Washington and fed up with the way Washington does business in the blow-dried hair ways of Washington. And Cain has tapped into that.

Well, he's right, but he's right up to a limit, up to a ceiling. Because if you're going to become, as Mary says, a serious presidential contender, you have to go beyond the lines of make a crowd whoop and cheer and you have to be…

It's just a surprise to me, it looks like they're going to go after as many as they can.

There are going to be two major factors. One, do Republicans like the -- the person who's going to be the nominee? Do they ideologically agree with that person? But also electability is also a slice of the decision-making pie.

I think it continues to show how fluid and open the Republican race is.

It seems they really want to play a hand in this primary.

If I were President Obama, I'd be very careful about going after Mitt Romney on his flip-flops, where indeed he did change his position on gay rights and on abortion.

I find it an interesting new development in politics that President Obama's authorized his staff to -- they went after Huntsman, they have gone after Perry, they have gone after Romney.

If I were President Obama, I would be very careful about going after Mitt Romney on his flip-flops, where indeed he did change his position on gay rights and on abortion.

Barack Obama has so many more of those on his own which is when he was a senator, he voted against raising the debt limit and then of course he wanted to raise the debt limit.
