Iran is holding legislative elections in March 2024. In the previous election in 2020, the conservatives won in a landslide, taking 240 out of 290 seats (83%), due in-part to the Guardian Council’s disqualification of reformist politicians.

“supermajority” means two-thirds (66%+1) of the seats in the Islamic Consultative Assembly.

Wikipedia’s tally of Principlists in parliament will be used for defining “conservatives and hardliners."
