Look, Trump will get the bulk of Cruz’s support with him or without him. If Cruz honestly is what he claims to be, he’s on the same side as Trump. It makes sense for him to make peace.
You Trump fans keep ignoring the point. This isn't about Cruz accepting. It's about Trump offering.
If Trump offers Cruz a Supreme Court, it will confirm that Trump is the biggest liar of all the candidates. And the Trump cultists are proud of the fact that they don't care.
Trump won't be getting my vote, regardless of who he tries to bribe for delicates. However, if Cruz were to accept any such bribe from Trump, I would never support him again.
