There are no non-theocratic politians in Iran, they do not get approved for standing in an election.

Ahmadinejad has taken a number of opportunities to take subtle swipes at the clerics, including Khamenei, questioning in public for example whether their edicts are directives or suggestions. He has also tried to consolidate more power for the presidency, trying to create a parallel foreign ministry and by making political appointments he's not entitled to make.

Hardly the only President to wrestle for power against the Leadership Council, but this was such an obvious historical bullet point it was easy to find citation on. These are not Theocrats in any meaningful way and they break from religious leadership as they see fit. What's more, Khamenei himself came to his office over the objections of numerous members of the Assembly of Experts, having to argue for special dispensation precisely because he was neither a marja' or ayatollah prior to assuming office. It does not seem as though Iran lacks for partisan wrangling or strict adherence to religious dogma.

Meaning all 12 positions of the body that decides who can stand for election are either appointed by the supreme Leader or appointed by someone with direct allegiance to the Supreme Leader.

Such weasel words. You might as well claim no one in the US can stand for election without being approved by a sitting President or someone with direct allegiance to a sitting President. Then wave your hands at the national party apparatus and the various partisan elected county clerks.

No politician rises on their own accord. They all require networks of supporters and compatriots to climb into higher office.

The constituents send up theocratic politicians because there are no other politicians

I asked you to show me a Middle Eastern government more liberal than President Masoud Pezeshkia’s Independent Reformist coalition.

All you could rebut with is whining at the nomination process being not to your taste.

I don't think you actually know or care for the state of Iranian democracy one way or another. All you seem to care about is that they've replaced a Western friendly military dictatorship with a religiously inclined elected parliament.

A theocrat has the ultimate power
