This was what I took from her statement as well.
To flesh that out:
1) In my opinion, she can now go "silent mode", and will. As stated, the onus is on TRUMP to pull back in moderate Republicans.
2) He won't be able to do it... which means he gets clobbered in November.
3) This allows Haley to IMMEDIATELY take the lead on "How do we fix this?"
4) I believe this is her game. To remake the next version of the Republican Party into "not-MAGA". That doesn't EXCLUDE them from the Republican Party. But there would now be a "repudiate Trump" reason (he gets clobbered again in November) to fix the GOP. And the agenda would no longer be to "bootlick Trump no matter what". She should be able to take some of Trump's talking points ("tough on the border") and redefine them as Republican and not Fascist. As long as Trump the "strongman" (hahahahahahahahahahaha!!!) is on the docket, it's all about his fascist cult and not about a two party system under American Constitutional Democracy.
5) She was pulling hard on Centrists (Republican or Indie), moderate Republicans (the few who remain), and right-leaning Indies, specifically. This is where she is going to start efforts on a "New Republican Party". I have no idea where this goes/ what kind of policy platform they might set/ whether MAGA can be roped in, or not... etc.
6) But demolish Trump in November first, and then see what happens.
I think this is her game plan.
