A Republican hero since overcoming a union-backed recall effort this past summer, Wisconsin Gov. Scott Walker (R-Wis.) praised Mitt Romney for choosing  House Budget Chairman Paul Ryan as his running mate. 

"Gov. Romney not only showed that he has the experience and the skill to become president, he showed he has the courage and the passion to become an exceptional president," Walker said. "With this pick he showed that the R next to his name doesn't just stand for Republican, it stands for reformer." 

Walker got the most enthusiastic reception of any speaker yet. But his actual speech was mild-mannered; he avoided red meat in favor of anecdotes about economic success.
