John McCain is no friend to the right..

The liberal senator fights conservative with more ferocity than he ever did Barack Obama when he was running against him for President.

Now he stepped over the line with an outrageous attack on a conservative senator.

The Senate was debating a bill that would push forward the nation of Montenegro’s campaign to join NATO.

McCain supported the legislation.

But some conservatives balked.

They see the legislation as deepening America’s military and financial obligations.

Montenegro would be the 29th nation to join NATO.

The United States is on the hook militarily and financially for defending those countries.

Conservatives believe America’s can’t afford to be the world’s policemen.

Among this group of skeptical conservatives is Kentucky Senator Rand Paul.

McCain was asking for unanimous consent to move the bill forward and Paul objected.

Now there will be debate on the bill.

McCain responded with fury.

He smeared Paul as a direct employee of Russian President Vladimir Putin.

The Daily Beast reports:

“McCain continued: “If they object, they are now carrying out the desires and ambitions of Vladimir Putin and I do not say that lightly.”

Several moments later, after the 80-year-old senator asked for unanimous consent to move the bill forward, Paul took the mic to raise his objection before dramatically exiting the room.

In response, McCain began railing against Paul, his voice trembling with anger: “I note the senator from Kentucky leaving the floor without justification or any rationale for the action he has just taken. That is really remarkable, that a senator blocking a treaty that is supported by the overwhelming number—perhaps 98, at least, of his colleagues—would come to the floor and object and walk away.”

He then directly connected Paul to the Russian government: “The only conclusion you can draw when he walks away is he has no justification for his objection to having a small nation be part of NATO that is under assault from the Russians.

“So I repeat again, the senator from Kentucky is now working for Vladimir Putin.”

Paul responded by calling McCain “unhinged” and “past his prime” in an appearance on Morning Joe where he criticized the idea of expanding NATO to include Montenegro.

Real Clear Politics reports:

“PAUL: You know, I think he makes a really, really strong case for term limits. I think maybe he’s past his prime; I think maybe he’s gotten a little bit unhinged.

I do think that when we talk about NATO, there can be a rational discussion about the pros and cons of expanding it. We currently have troops, combat troops, in about six nations. We have troops actively just stationed in probably a couple dozen others. We have a $20 trillion debt. And one of my favorite articles of the last couple years is one that talked about the angry McCains, and if they — if we put active troops and got involved in combat where McCain wants us to be, they put a little angry McCain on the globe, on the map. And it’s virtually everywhere. So his foreign policy is something that would greatly endanger the United States, greatly overextend us. And there has to be the thought whether or not it’s in our national interest to pledge to get involved with a war if Montenegro has an altercation with anyone.

There’s also another argument, is that when you ask the people of Montenegro, only about 40 percent or slightly less are actually in favor of this. They are close to Russia, they’re close to being sort of, like Ukraine, in the transition from Europe to Asia. Perhaps it would be good to be like Switzerland and be more neutral and trade with both.

So, there’s a lot of considerations but to call someone somehow an enemy of the state or a traitor might be considered by most reasonable people to be a little over the top.”
