(As Evan Siegel noted in a comment, it's odd that the Iranian side of this comparison doesn't mention the mediating role of the Guardian Council, which needs to approve all aspiring candidates and routinely disqualifies almost all of them. We might add that women and members of religious minorities are ineligible, and that voters who complain too loudly about stolen elections can get imprisoned, beaten, and sometimes tortured.)
In case you've been wondering who ultimately controls elections in the US, now you know.
