"We want to lose this election for strategic reasons!" is an amazing bit of #Analysis that I had thought would be restricted to Atlas, but alas. Nevermind getting to select a SCOTUS nominee or doing something other than obstinately rejecting every bill for another four years; we really just ought to demoralize our opponents.
I don't think you'll find a soul who would argue that losing in 2012 was good for Republicans, or bad for Democrats, given the consolidation of Obamacare.
I think the case for 2016 is unprovable but strong.
I won't deny that there were downsides to winning in a year when there were deep divisions in the electorate. To go from that to "it would have been better to lose" is a pretty big leap though.
