* A sobering post from David Dayen about why Wisconsin portends further decline for unions and how Scott Walker’s plan to eliminate them has been working brilliantly for months.

* E.J. Dionne has a sharp look at the left’s missteps in Wisconsin and the “cool realism” that unions will have to exercise in the future about which fights they should pick and what they’re up against.

* Ron Brownstein on how the Wisconsin results cast doubt on Obama’s chances to win in blue-collar-dominant states, and why that puts renewed pressure on him to win in the west to offset Rust Belt losses.

* Jonathan Chait, on what’s next:

Walker’s win will certainly provide a blueprint for fellow Republicans. When they gain a majority, they can quickly move to not just wrest concessions from public sector unions but completely destroy them, which in turn eliminates one of the strongest sources of political organization for the Democratic Party. And whatever backlash develops, it’s probably not enough to outweigh the political benefit. Walker has pioneered a tactic that will likely become a staple of Republican governance.

* Kevin Drum says Walker is a harbinger: Modest growth means a decade of “trench warfare style of politics, with everyone fighting over scraps because the pie isn’t growing as fast as it used to.”

* Scott Walker, “courageous”? Citizens for Tax Justice shows that Walker’s actual policies “courageously” cut programs for the poor while giving tax breaks to the wealthy and corporations.

* Andrew Sullivan, on the method behind Romney’s amnesia strategy:

this is a core goal of the total obstructionists in the GOP: to prevent Obama from doing anything past his first two years to alleviate the sluggish recovery, so they can then blame the subsequent sluggishness on him, and then cover the whole cake in surreal, deceptive, cynical Rovian icing. It may work. Which is why we need to do what we can to expose the lies as insistently as we can.

* Paul Krugman, on the fiscal hawks’ claims that we can’t spend to create jobs because we must reign in the deficit immediately for the sake of our children:

Everything we know says that this generation will never — never — recover from the terrible job market into which it has graduated. But hey, we can’t do anything about that; we must have austerity, for the sake of the next generation.

* As Domenico Montanaro notes, it sure is odd that so many Republicans are praising Bill Clinton for saying he doesn’t think we should extend the Bush tax cuts permanently.

* And Steve Benen is funny on Mike Huckabee’s odd claim that Americans who don’t watch Fox news will assume Obama is doing a great job.

What else?
