So much for Bobby Jindal

Louisiana Gov. Bobby Jindal's departure from the 2016 Republican presidential race hardly qualifies as the biggest surprise. Even when his campaign made sense on paper, there was concern that he wasn't charismatic enough to succeed in the Age of Obama. (Remember that State of the Union response?)

But there were a few things we learned from his relatively short-lived campaign.

1. So much for governors. The conventional wisdom was that with the Republican-controlled Congress polling so poorly, GOP might turn to a governor this time around. Four of the last five presidential elections the party has won was with a current or former governor as the nominee. Executive experience was seen as an asset after witnessing some of Barack Obama's shortcomings. Anecdotally, a lot of activists and primary voters this writer talked to said they wanted a governor.

Well, the economists call it revealed preferences. Rick Perry, Scott Walker and Jindal were the first Republican presidential contenders to exit the race. All are current or former governors. Jeb Bush and Chris Christie have been in more or less steady decline. John Kasich had a promising beginning but seems to be losing steam even in New Hampshire.
