I can see by reading the posts here that many people believe that the Supreme Court can do anything it wants anytime it wants, but judges are very conscious of their limitations. The judiciary has no army. it depends on the executive branch to enforce (give meaning to) its opinions. The judiciary has no independent source of funding. It relies entirely on the Congress and the President for funding. Without the continuing support of these other branches of government, the judiciary has no power at all. Without some basic level of continuing support from the public, the power evaporates.
“judges are very conscious of their limitations”
Sorry. The US Supreme Court has no problem at all with creating law out of thin air. Think abortion, or the “right” to homosexuality...kind of hard to find THOSE in the US Constitution!
If Cruz ran, and one state put him on the ballot and another refused, you would have a valid federal case, just as Florida’s recount methods fell under the federal judiciary.
