* Breaking: Wisconsin Dems are open to, and are actively considering, a plan to retaliate against GOP shenanigans by running their own candidates in GOP primaries before the recall elections, the spokesman of the Wisconsin Democratic Party confirms.

Republicans have embraced a scheme in which they are likely to run candidates against Dems in Democratic primaries in order to delay the recall general elections, in hopes of making it easier for the targeted GOP state senators to survive. Now Dems, for all the reasons I laid out below, are seriously considering doing the same in Republican primaries, though no decision has been made. Graham Zielinski, the Wisconsin Dem party spokesman, tells me:

Our goal remains the same: To have these recall elections that have been called for by tens of thousands of Wisconsinites, free of the blatant fraud that the Republicans are engineering in an unprecedented and cynical way.

But we also understand that this fight is too important to have with one hand behind our backs. So we’re exploring all our options right now. This transparent Republican attempt to game the system and throw Democracy under the bus by running these fake candidates won’t go unnoticed by Wisconsinites. But we understand the stakes and we will do what it takes to ensure that this fight takes place on a level playing field.

Full context and backstory here.

* Paul Krugman, commenting on the unreleased methology of the McKinsey study faulting the Affordable Care Act, nails it:

One has to assume that there was something terribly wrong with the study. At any rate, nobody should be citing it until or unless McKinsey comes clean. Oh, and if you ask me, this is a lot more important than some sex scandal.

That is definitely going to hurt.

* And it’s getting worse: Sources within McKinsey are reportedly upset that the study’s methodology was below the firm’s standards.

* The Post has a terrific and detailed tick-tock explaining the Newt implosion.

* As Steve Kornacki rightly notes, the only people who were suprised by Newt’s epic implosion were media figures who deluded themselves into imagining his presidential campaign was anything more than an exercise in Megalomania.

* A conservative critic of Tim Pawlenty’s economic plan gets it exactly right: “Pawlenty’s speech reflects what Republican primary voters are demanding: detachment from reality on fiscal issues.”

* Wow: A new analysis finds that T-Paw’s economic plan would cut taxes by $11.6 trillion. Really, though — who says you can’t do that and raise revenues at the same time?

* House Dems demand that the White House push for an end to the Bush tax cuts for the rich as part of the debt ceiling deal.

* Joan McCarter finds some evidence that voters — unlike Beltway commentators and Dems — may be less in thrall to the Beltway Deficit Feedback Loop than we might have thought.

* Mitt Romney is skipping the Iowa straw poll to lower expectations in a state he’s not likely to win anyway.

* And fun stuff from Jason Linkins, who flagellates himself and the Huffington Post for wasting their own time and newsroom resources on the Sarah Palin emails.

What else is happening?
