OMG, there’s a “virtual Tea Party of the left”! Who knew?!

From View From the Left by Peter Baker:

Just as Speaker John A. Boehner has been under pressure from his right, Mr. Obama faces a virtual Tea Party of the left that sees his compromise as capitulation.

No kidding?  Where is this “virtual Tea Party of the left”?  You have piqued my curiousity…  There are apparently some differences between this left-wing Tea Party and the right-wing one however:

The main difference is that in the Obama era, the Democratic establishment has been less influenced, or intimidated, by the left than the Republican establishment has been by the right. Liberals have not mounted sustained primary challenges to take out wayward incumbents the way conservatives have.

So, Peter, what you’re saying is that, setting aside their respective influences on election outcomes, they’re similar.  I see.  Mr. Baker goes on:

But the wave of grievance from liberal activists, labor leaders and economists suggested that the uneasy truce between Mr. Obama and his base that held through the campaign season had expired now that there was no longer a threat of a Mitt Romney victory.

Mmm…  So the people who did the vast majority of the groundwork to get him elected in 2008 and re-elected in 2012 – the people he’s pretty much stiffed for the past four years – you think they might be less inclined to suck up to him now that he’s not up for re-election?  Yeah, I could see that happening.

From a policy standpoint, Pres. Obama governs like a sane Republican – well, “sane Republican” if your working definition is restricted to a generation or two ago when such a species still existed. (Obama as moderate Republican?  Hell, yes.  See, e.g., Obamacare.  The ACA can be traced back to a Heritage Foundation paper for chrissakes.)  Given that, why would anyone who believes that center-left public policy generally works a lot better than center-right public policy be enthusiastic about him?   Please feel free to offer your insights.
