That's a nice line, and there is some truth to it. The GOP spent like sailors on shore leave for a number of years, and deserve the whipping they get on the issue. But it is also true that if the GOP is like an arsonist in the job of fire marshal, then it is just as true that giving the gig to a Democrat would be like turning over the keys of the fire department to a pyromaniac.
The difference? An arsonist sets fires because he gets paid to do so; a pyromaniac sets them out of compulsion - he cannot stop himself.
