President Obama signs the landmark health care reform bill in a White House ceremony this morning at 11:15 a.m. ET. That and the day’s other political news in the TPMDC Morning Roundup.

Rep. Randy Neugebauer (R-TX), of “baby killer” fame, tells a local TV station: “I did believe, and still believe, that that Senate bill is a baby-killing bill.” Watch.

Late Update: Neugebauer and his wife also recorded a video that they posted on his campaign’s YouTube account.

Bibi Netanyahu gave his speech this evening at the annual AIPAC conference. And it amounted to one big ‘shove it’ to the president and the administration.

None of the Republicans’ angles on torpedoing the reconciliation package in the Senate seem that likely to succeed. But they staked their greatest hopes on the claim that the reconciliation bill impacts Social Security, which could make it out of bounds in the reconciliation process. But tonight Senate Parliamentarian Alan Frumin shot that one down.

The Chamber of Commerce, a key anti-Reform player and spender, is telling the GOP they can count them out on any campaign for repeal.

There’s a lot of nonsense out there about constitutional challenges to the Health Care Reform law on various ‘state sovereignty’ grounds. That’s nonsense. The Nullification Crisis and Civil War settled those issues. But the more serious challenges are based on extremely forward-leaning conservative arguments about the ‘commerce clause’. It seems very out there. Comical almost. And with your average Court, I would think it a trivial concern. But this Court, particularly the four most conservative members, have shown themselves to be not only so ideological but so activist and even so partisan that I’m not sure you can really put it past them. We’re going to do some poking around to find out more, particularly views on this question among the sort of legal academics and would-be judges who cluster around the Federalist Society.

Just to be clear, I’m not saying I consider this at all likely. But I’ve seen a number of things happen lately that I didn’t think at all likely. So I’m watching.

RNC chairman Michael Steele: Yes, health care reform is Armageddon. Watch.

Any Republican criticism of Rep. Neugebauer’s (R-TX) outburst last night? Any of the Tea Party hate speech over the weekend? Did I miss it?

These gentlemen seem to be wondering too.

Late Update: More from Jim Clyburn here.

Did you see the huge march this weekend in DC? Tens of thousands turned out. Maybe even 100,000. Tea Partiers? No, the big pro-immigration march that got virtually no press attention at all.

In today’s slideshow, here’s some of what you missed.

One party always wants to “fire” the other party’s leaders. That’s our system. But something seems little weird to me about the RNC’s new Fire Pelosi website (which the official GOP.com website now goes to). Why is she engulfed in flames? Is she being roasted alive? Or suffering eternal damnation and hellfire? How big a demotion is she supposed to get?

Even for condemning the country to socialism and tyranny, isn’t this excessive?
