Right now, his vote does not matter.
Hopefully, he changes his mind is just enough dems change theirs.
The only time he changed his mind was on January 6, 2021, when he changed his originally planned vote to reject Biden's electors, and came back after the temporary shutdown, spewing the lies of the media about what happened that day, and voted to accept Biden's fraudulent electors. He's a loser, and an opportunist.
