This is pretty much how I see it too. I agree that he's an opportunist, but there's still tremendous political value in sticking to the Republican party line on this issue, even if he personally does not benefit from lobbying. However I do believe that he would flip sides if it seemed like popular sentiment was flipping, and he would claim that he's been in favor of it all along. If this program is successful, that might actually happen, and of course he'll be sworn in by the time the broader program is rolled out, and he'll take credit for it while finding some way to blame Biden for not having it sooner (even though he had 4 years of his own to do it and took no action).
