From Scott Grannis:
I’ve long been a big fan of Paul Ryan, so I am thrilled with Romney’s VP choice. The Romney-Ryan ticket represents the single best hope for reforming our runaway government and reviving our sickly economy. If the people do not respond to this overwhelmingly in November, then the future of our country will be in serious doubt.
UPDATE: For a fairly comprehensive look at the origins of Paul Ryan’s approach to policymaking, see this article by John Podhoretz.
