The kernel of truth in blaming Obama

Greg Sargent and Steve Benen share a tic.  Almost daily, both expose the big lies and small lies on which Romney's economic case is founded.  Almost invariably, after highlighting the falsity in the Romney narrative, they warn: it could work.

One underlying assumption, inculcated by the political scientists, is that voters blame the president for the state of the economy because they don't understand how limited the powers of the presidency are, particularly when the out-party is determined to block all action proposed by the president. Hence Benen today:

What's Obama's peer group job creation ranking? Way better than 47th of 50

Romney's job creation record as governor of Massachusetts bears a striking -- if superficial -- resemblance to Obama's as President: a first year of job losses followed by three years of weak growth (actually, for Romney, a rather strong final year following two near-flat years).

Romney has been attacking Obama's job creation record since...forever.  You know the drill: Obama made the recession worse, Obama isn't working, nearly a million jobs lost on his watch.  This week, as the Obama team turns the tables and broadcasts that Massachusetts ranked 47th out of 50 states in job growth during Romney's tenure, the Romney camp finds an excuse: you can't blame him for first-year job losses. Of course, if you give Obama that pass, the country has gained nearly 4 million jobs on his watch.  Or, as Michael Tomasky calculated: excluding each executive's first year, and through April of their fourth year, Obama has presided over 2.35% job growth, Romney over 1.9%.

Hence, two Obama spox pounced this morning on Twitter:

Jim Messina: Romney economics: Under Romney, MA fell to 47th out of 50 on job creation. Under POTUS, we see 27 months of private-sector job growth.

Stephanie Cutter: Romney campaign undercut its entire strategy by arguing that he inherited bad economy so 1st yr shouldn't be counted.

What's needed to concentrate fire, it seems to me, is an apples-to-apples comparison to Romney's 47/50 ranking, or a reasonable facsimile thereof. In reality, any local economy in any given period is sui generis; Rick Perry is not a "better" job creator than Mitt Romney. But with Romney shamelessly manipulating the stats to attack Obama, it's fair to come up with a "peer group" for the US during Obama's term.  And what could be fairer than the OECD, which includes Korea, unemployment rate 3.7% at present, and Japan, clocking in at  4.5%?  So let's have a look.
