80k out of 1.05mil is 7.6%. If you consider that 7.6% of Republican primary voters are considering voting for Biden, then those numbers look a little different. If 7.6% of Republicans in Ohio who voted for Trump in 2020 decided to vote for Biden in 2024 then that could certainly change the outcome of the election.
A 7.6% change would result in Biden having 2.919 million votes and Trump with 2.914 million votes. While some of these Haley voters probably already voted for Biden in 2020, there could still be a large enough shift in voter choice to make a difference. Especially if the Democrats have a large turnout in the general election. After the bullshit that Republicans have been up to lately, I think that people are at least angry enough to go out and vote out of spite.
Edit: Nevermind, I’m probably wrong. I didn’t realize that Ohio has open primaries, so these numbers probably don’t matter.
