The language is slanted here - Rudy’s quote is framed by the abortion issue, but in actually I read him as supporting state’s rights to choose whether or not to allow and/or support financially.
He makes no promise to protect “abortion rights” across the board or to fund them universally.
Legally it’s a simple finding of fact and finding of law — rational stances both; that abortion is legal at the current time, and that he is in no position to ban it, or deny state’s rights to support it financially in its current legal state, defined as an at times “necessary” medical procedure.
States rights!!
That sounds familiar...
