Scott Walker's own limitations did him in

It’s easy to say Scott Walker dropped out of the Republican presidential race because he ran out of money. But he ran out of money because of his own limitations as a candidate — limitations that have been in plain sight for quite a while.

Walker surprised the political world in late January when he delivered a wow-’em speech at an Iowa Republican gathering. The GOP activists there already respected Walker for his record as governor of Wisconsin, but most expected a lackluster, even boring presentation from a man who had not, up to that point, set the campaign trail on fire.
