Ryan is one of those with such potential, but he’s shown nothing since getting the VP nod. He did a great job on 2011 and 12 presenting a course of action. Then we went AWOL and sucked into the DC blob.
I think Ryan spent too much time around Mitt Romney during the 2012 election and caught a terminal case of RINOitis, that was the point when he seemed to go from a pretty reliable conservative to just another mushy, inside the beltway RINO.
