Trump’s positions on those issues have not changed. If you want to argue that DeSantis is more conservative than Trump on abortion, that’s fine. Maybe he is. But that doesn’t mean Trump has moved left on the issue.
Trump’s SCOTUS picks has given the power back to the states on abortion. That’s his major achievement on the issue and, as he puts it, it has leveled the playing field, allowing any future legislation on the issue, whether federal, state, or local, to be decided on an even footing and not giving pro-abortionists an advantage right out of the gate.
As far as Gun Control and groomers, there’s no basis on which to claim DeSantis is stronger on those issues than Trump. And don’t bring up Disney as a counter example. Trump never sided with Disney as far as their criticism of the “Don’t say gay” bill. He criticized DeSantis’s response to that criticism for being poorly thought through and being designed more for optics than anything else.
There is some basis, as Trumpvwas willing to compromise on an Assult Wepons ban.
