Econ bloggers for hire?

Tyler Cowen suspects so:

Here is Dani Rodrik defending Hillary on trade, here is Paul Krugman. Here is the very good critique from Clive Crook. So what's up? My uninformed default assumption is that Hillary wants to win the Iowa caucases. That means her goal is to signal protectionism to Iowa activists and voters, and sophisticated non-protectionism to the more trade-oriented elites and donors. Congratulations if you were able to pick out the latter signal, but don't confuse it with a defense of what she said, why she said it, or when she said it.

Yet another corollary coming out of this?
