The wording isn't exactly clear, but it doesn't say what you think it does. Alaska approved ranked choice voting and open primaries in 2020. Leman was part of Yes on 2 which was an effort to repeal RCV and go back to closed primaries. Outside groups helped fund the opposition campaign to say no to the repeal. The group trying to enact the repeal raised very little funding. So what he said isn't contradicted by the numbers presented.

I'm dissapointed that there seems to be so much impetus to go back to first past the post in Alaska. That might slow down efforts elsewhere in pushing for RCV.

I don't think that is a call out. Pretty sure it supports the statement. They said they were an advocate for repeal. Repeal would mean voting yes on the ballot measure. So no on 2 having 14 mil was against repeal and that's supporting their statement.

Either you're misreading or I am misreading, because going by this, Yes on 2 is the campaign in favor of repeal – i.e., the one Leman is in favor of – and the latter paragraph is backing up what he says by saying No on 2 spent more than Yes on 2 by a 100x difference.
