Quirky factoid: Wisconsin Governor Scott Walker has raised $48 million to get a 48% approval rating.
Walker raised $11 million in campaign funds to win the governor's office in 2010. And he raised an additional $37 million to survive the 2012 recall.
Of course, interest groups backing him spent many millions more on his behalf, including nearly $23 million in 2012 alone.
The governor's approval rating is holding steady. Polling done in early summer mirrored the latest opinion survey, with public approval of his performance at 48%.
