From Meet the Press, Joe Scarborough and Dan Senor think it's just fantastic that the GOP is running their "moderates" out of the party. Great game plan guys. Keep this up and maybe the GOP can get down to 15% instead of 20% of Americans that want to identify themselves as Republicans.

GREGORY: All right. Let--I've got about a minute left here. I want to talk politics here. Joe Scarborough, there seems to be, within the Republican Party, a litmus test going on. You had Sarah Palin on Facebook endorsing the conservative independent candidate in New York for that congressional seat in the 23rd district.

SCARBOROUGH: Mm-hmm.

GREGORY: Is this what's going on inside the Republican Party, this sort of run to see who can be the most conservative as a means of retaking power in 2010?

SCARBOROUGH: Well, it, it depends. How could any Republican, how could--let me strike that. How could any conservative be against the person that the Republican establishment in D.C. is for if they're conservatives? This woman, this Republican candidate, is for card check. She was for the Obama stimulus package. She has voted for taxes. I mean, she's been one of David Paterson's best allies. Why would a conservative support that Republican? This is, this is just one more example of how the Republican Party in Washington, D.C., is so disconnected from conservatives.

SENOR: You're seeing a revolt all over the place. In Joe's state, in Florida...

SCARBOROUGH: And, and I'm saying...

SENOR: ...Marco Rubio, who's running against Charlie Crist for the U.S. Senate...

SCARBOROUGH: Yeah.

GREGORY: Right.

SENOR: ...the Republican establishment in Washington rallied behind Charlie Crist because he was supposed to deliver the general election. Suddenly the polls in the Republican primary are closing, all the Republican primary conservative support is getting behind Marco Rubio, who's the start-up candidate.

SCARBOROUGH: And by the way, people love...

MAYER: This can't be good for the Republicans that have their own base being fractured, is it?

SCARBOROUGH: No. It's great for the Republican Party because...

SENOR: It's fantastic for the Republican Party.

SCARBOROUGH: ...when I, when I ran in 1994, the Republican Party on the state, national and local level tried to run against me a moderate Republican. And I'm not talking, I'm not talking abortion or gay marriage, I'm talking taxes and spending, small government. That's great to reinvigorate the base.

GREGORY: All right. And the president's out there for two big governor's races in New Jersey and Virginia this week, which a lot of people will see as some kind of referendum. We're going to leave it there.

The Khyber Pass, through which 70% of US military logistic needs for troops in Afghanistan and enough food to keep Kabul from crippling famine passes, was closed again Tuesday. By my count, that makes the fifth time since the 30th of December. Militants blew up a key bridge, which was apparently unguarded at the time, only a few miles from the Pakistani regional capital of Peshawar, home to the main military garrison for the entire border region.

It was not immediately clear whether supply convoys could reach Afghanistan through alternative, smaller routes in the region. An official in the area, Fazal Mahmood, said repair work had begun on the bridge.

The top U.S. military spokesman in Afghanistan said traffic was already flowing again after the attack. "They made a bypass," Col. Greg Julian said.

Hidayat Ullah, a government official in the Khyber tribal area, said the 32-foot-long (10-meter-long) bridge was about 15 miles (25 kilometers) northwest of the main city of Peshawar.

Pakistan has dispatched paramilitary escorts for supply convoys and cracked down on militants in Khyber, but attacks have persisted in an area that up to three years ago was largely free of violence.

Col. Julian, Petraeus' spokesman, also made much of Petraeus plans for an alternative route for supplies through former Soviet states. Petraeus had last month described such a deal in very 'slam-dunk' terms, but there's an unforeseen problem. As I wrote was likely back in mid-January, Kyrgyzstan's president has announced, via the Russian press, that the US airbase in his nation is to be closed.

Kyrgyz President Kurmanbek Bakiyev spoke on a visit to Moscow minutes after Russia announced it was providing the poor Central Asian nation with billions of dollars in aid.

Bakiyev said when the U.S. forces began using Manas after the September 2001 terrorist attacks, the expectation was that they would stay for two years at most.

"It should be said that during this time... we discussed not just once with our American partners the subject of economic compensation for the stationing (of US forces at the base)," he said on Russian state-run TV. "But unfortunately we have not found any understanding on the part of the United States.

"So literally just days ago, the Kyrgyz government made the decision on ending the term for the American base on the territory of Kyrgyzstan," he said.

General Petraeus may have been blindsided by this news. He had previously claimed that the US airbase in Kyrgyzstan would play an important part in plans to develop a new supply line into Afghanistan, but that seems to have been well before Russia began pressuring the Kyrgyz government. His spokesman today dismissed the Kyrgyz leader's announcement as "political positioning".

That might be true. If so, the question former diplomats I've been talking with are asking is: "what does Russia want in return for an Afghan supply route?"

Interestingly, Afghan president Karzai was reported recently as considering a deal with Russia for military assistance. For Russia, Afgfhanistan is strategically placed between potential competitors and potential allies and Russia has always been interested in a military presence there if it could be accomplished without the kind of armed resistance that led to its withdrawal in the '80s. But there could be bigger prizes to seek too - like a new START agreement.

The Great Game continues with some new players and as ever one of the most powerful hands is held by whoever can open or close the Khyber - whether by direct action or deliberately looking the other way while local "armed entrepreneurs" do it for them. (I mean, really - a crucial bridge utterly unguarded only 15 miles from Peshawar?) Whoever has the Pass has the gorah by the short and curlies. As it stands right now, Pakistan is only reminding the US and its allies of that eternal truth. But with a US troop surge into Afghanistan in the offing and Pakistanis increasingly irate at airstrikes into their territory, the ability to cut off fuel and food to those troops and to the Afghan capital is a powerful potential weapon

Of course, as I noted last month too, there's already a perfectly good brand-new alternative road and rail route into Afghanistan...through Iran.
