Marco Rubio and Ted Cruz did their best Donald Trump impersonation. All three unleashing an unprecedented string of insults and attacks fit more for a barroom than a presidential debate stage.

I think that`s a plausible strategy. But I also think there is a case to be made that [Hillary] Clinton actually in some ways is best served by almost ignoring him and the sort of marginal voters that there are to get for Hillary Clinton are voters who already think poorly of Donald Trump and are not sold on her.

In the case of Philando Castile, we believe he was complying, it might have been precipitated by a police officer telling him to open the glove compartment.We have other examples in which people have met the same fate when they appear to be complying. Yet the way that the system tends to operate and the way the police when you talk to them view that situation is they are looking for things that trigger their perception of threat and that`s a highly subjective judgment.

Not only has [Donlald] Trump adopted that tactic attacking usual suspects like The New York Times and The Washington Post, but he`s turning it back on the conservative media who invented it in the first place.

Sarah Palin, suggesting her son`s arrest on domestic violence charges was a result of post-traumatic stress disorder and partially due to President Obama`s lack of respect for men and women in uniform.

Ted Cruz who`s been gaining on [Donald] Trump in Iowa and is polling ahead of him in the latest Monmouth poll would be quite reluctant to criticize Trump`s plan saying simply it is not his policy.

I mean,[Marco] Rubio, he`s having fun. I`ve got to say I`ve never seen him enjoy himself out there so much. He`s found way to get under his skin. So, he`s found way to look like he`s somebody that is a force, which has hasn`t so far.
