This is the exact reason to discard “what type of Supreme Court justices would they nominate” as a criteria in judging a candidate worthy of being President. Reagan had Sandra day oconnor and Scalia. W had Roberts and Alito. Saying a Cruz nominee (for example) is more likely to be conservative is completely unfounded “logic”. Justices change in unpredictable ways sometimes when they get in the Court. Cruz could nominate the most conservative person in the country and history says they may not remain that way on the Court.
Too many here just cannot see that point. If a candidate is conservative then, ipso facto, all appointed by him have to be the same and likely they imagine there is no difference between someone who is a conservative and someone who is an Originalist.
Too much magical thinking going on for me.
