A would-be Russian presidential candidate with a reputation for opposing the war in Ukraine is poised to garner enough signatures to run against Russian President Vladimir Putin in March — provided that the Kremlin allows his candidacy to proceed.

“We’ve already collected 101,000 signatures,” Russian politician Boris Nadezhdin announced Tuesday, per a Meduza translation. “These signatures are not perfect! We’ll need to submit 105,000 flawless signatures to the Central Election Commission. Ones that can’t be challenged.”
