Harry Reid tells reporters that he and Leader Pelosi have been summoned to the White House, on their way.

McConnell says he’s spoken to Obama and Biden within the hour, expresses confidence a deal can be reached.

Wisconsin Republican admits she compared public schools to Nazi Germany.

I’ll very much believe it when I see it. But there has been an escalating chorus on the Dem side over the course of the day that if there’s no agreement reached, President Obama should invoke authority under the 14th Amendment to continue paying the federal government’s obligation after August 2nd.

I do not think it’s at all likely to come to fruition. But in such a volatile climate as we’re likely to see over the next 48 hours, all developments are worth noting.

Dems prepped for tonight’s debt limit vote to fail as Republicans push stealth Social Security to kick in automatically as ‘trigger’ if next round of cutting doesn’t happen.

Not really relevant to the immediate situation. But for future reference let’s remember that the entire concept of a debt limit ceiling is ridiculous. If the Congress votes to spend more than it will take in in tax revenues, that is a vote to borrow money. Period. For Congress to vote once to borrow the money and then have to vote again to borrow the same money is silly.

That’s not to say this has any constitutional relevance; Congress has broad latitude to do stupid things. But this was always a silly way of doing business — which is the reason why no other major country has a similar procedure — a time bomb waiting for one of the two parties to decide to play Russian Roulette with the nation.

Sen. Reid (D-NV) announces he’s delaying Senate vote until tomorrow at 1 PM to give time for negotiations currently underway at the White House.

Nothing’s over until it’s over. Surely that’s a truism the last few weeks have proven over and over again.

That being said, the contours of a compromise deal to break D.C.’s deadlock, and increase the debt ceiling, are now coming into focus.

A reminder that the best place to keep across the weekend’s developments, as they happen, is in our TPM Livewire. Check it out.

As TPM’s Evan McMorris-Santoro reports, progressive groups are hopping mad over the proposals leaking out on the debt deal’s final contours.

To judge from TPM’s inbox that fury is not isolated. Indeed, there seems to be a certain buyer’s remorse from some Democrats who backed President Obama in the 2008 primaries.

For instance, AF writes: “I am angry at myself for supporting Obama over Hillary Clinton. She knows how Republicans behave and she was no wimp.”

Other readers have been fantasizing about Clinton giving Obama a primary challenge in 2012.

So what do you think? Would Clinton have handled this better? As ever, feel free to use the link at the top right to send us your views.
