(WASHINGTON POST) — If Rick Santorum can pull out a narrow victory in Tuesday’s Michigan primary, he might have Democrats to thank.

Or at least, that’s how the theory goes.

For weeks now, political observers and politicians have been whispering about the impact Democrats could have on the state’s GOP primary, with the idea being that they would vote for Santorum in a concerted and deliberate effort to prevent Mitt Romney from winning — and prolonging the Republican presidential race in the process.

It even has a name: Operation Hilarity.
