Byron York in the Washington Examiner:
Romney’s gamble is that in the midst of an economic downturn, voters are ready to accept Ryan’s prescription for fixing the federal budget, in particular his proposals for reforming Medicare. Romney and Ryan are right that major changes need to be made, and at some point the voting public will accept that view, too. That day is coming. The question is whether it will arrive by November 6.
Certainly a bold move to choose such a vocal, polarizing figure as his running mate. Unexpected from the likes of Mitt Romney, and it further separates Romney's campaign from the haphazard mess that was McCain-Palin 2012. The VP debate should be a lot more potent this year, to say the least.
