Iranian "Elections"

I was intrigued by the headline, "Iran approves candidates," linking to an article about Iran's upcoming presidential election. From the article:

Campaigning has officially got under way in Iran's presidential elections, with just four people cleared to run out of the 475 who registered.

Iran's Guardian Council cleared four candidates, including Mahmoud Ahmadinejad, the current president, to run for election, Iran's Jumhuri-ye Eslami newspaper reported on Thursday.

The Guardian Council likely thinks they're "guarding" the people from themselves.
