Secretary of State Hillary Clinton has repeatedly denied that wants to run for the Democratic Presidential nomination against her boss, Barack Obama. But that hasn’t stopped those disappointed in Obama from pushing her to run.

But now there's a bizarre twist. This week, voters around the country reported a wave of annoying robo-calls from an anonymous group calling itself Hillary Run 2012. Suspiciously, the calls started right after two Democratic pollsters wrote an op-ed in the Wall Street Journal urging Obama to step aside for Clinton…

The group’s website claims they are a “project of the 99%” and links to an online petition urging Hillary to go for the nomination. But it identifies no administrator and gives no contact information, and so far journalists’ attempts at finding out who is behind it have come to naught.

The most obvious culprit would be Hillary supporters. But the sheer amount of robo-calls, their tendency to target journalists who will then publicize them, the co-opting of Occupy Wall Street’s popular slogan, and their occurrence in key battleground states have spawned rumors that conservative interests are actually behind them. After all, any Republican nominee stands to benefit from a fracturing of Democratic support for Obama, and no less a conservative than Dick Cheney has argued that Clinton should run.

Listen to a clip of the robo-call and make your own judgment.
