Rhode Island's state treasurer takes on public employee unions and her party (she's a Democrat) to tame an out of control state pension system.

So this is Gina Raimondo? The state treasurer who single-handedly overhauled Rhode Island's pension system and has unions screaming bloody murder? I had imagined her a bit, well, bigger. If not larger than life like New Jersey Gov. Chris Christie, then at least life-size. Ms. Raimondo couldn't be much taller than five feet, which may have caused some to underestimate her. That isn't the only thing that may have surprised people.

The former venture capitalist is a Democrat, which means that she believes in government as a force for good. But "a government that doesn't work is in no one's interest," she says. "Budgets that don't balance, public programs that aren't funded, pension funds that are running out of money, schools that aren't funded—How does that help anyone? I don't really care if you're a Republican or Democrat or you want to fight about the size of government. How about a government that just works? Put your tax dollar in and get a return out the other end."

Where is Pennsylvania's Gina Raimondo?
