No, he’s not misinformed; he’s blaming the Democrats.
Deflecting from the fact that the ever deepening horror show that was the Senate bill was a disaster that could cost the GOP seats, they now get to campaign for the next year on ‘Demoncrats stopped us from fixing healthcare!!!’
It’s a lie of course, but the GOP lies like they breathe. It’s all they’ve got left; their true agenda (dismantling the United States for the enrichment of their billionaire masters) isn’t palatable to the majority of voters, and they’ll have a harder and harder time supressing enough of the vote to win.
