I thought you were aware that Trump is completely unpredictable
He's not completely unpredictable. He lays out his beliefs and platform and follows through. He's over-calculating on the life issues.
His equivocated abortion stance is that he's become weaker on abortion than he was before. This accompanied by this week's roll out of his mandating IVF treatments is not going to help but hurt him at the polls, IMO. Pro-lifers MAY end up not casting any votes for president. Trump needs pro-lifers to vote for him.
If he secured the pro-life position, I think he wins without a problem. Now, if enough pro-lifers abandon him, I see it as 51% chance he wins.
Even without full pro-life support, he can win. Harris is struggling. She didn't get much, if any, of a post-convention bump. That's unusual.
