What's going on in Iran?

For many years the elected part of Iran's government was dominated by reformist politicians leading us to believe that the hard-line policies of the Islamic revolution were unpopular. But then, in the last few years, the unelected clerics decided that the reformist politicians would be disqualified from elections. However, Iran recently held an election which included candidates from various wavelengths in the political spectrum, including a reformist candidate or two. The result of this election was a victory for the most hard-line candidate. There have been reports of fraud but the news I've heard says any fraud doesn't appear to widespread and that, overall, the results should be considered valid. So what is does the mood of the Iranian electorate? Has it changed? If so, why? If anything, I would have expected some kind of backlash against the hard-liners for disqualifying the popular reformist politicians. None of the media I have been paying attention to has made any sense of all this to me yet.
