I suspect it was either that for face a primary challenge when his term is up. Plus no funds from the RNC, and no chance at a supreme court appointment....
I wouldn’t have Cruz replace Scalia. At this point he’s a roll of the dice...wait until we’re looking for an overwhelming majority
Ted finally woke up to reality: barring the cheating Democrat party stealing the election (in which case all H E double el will break loose all over America) Donald Trump will become the next POTUS and TC will be relegated to the political dust bin of history.
While TC's support is much more than "a day late and a dollar short", it is better late than never.
That said the overwhelming, self-inflicted damage to Ted's political career cannot be undone. He has revealed himself for the unprincipled, oath breaking, back stabbing GOPe establishment political hack that he really is. His own constituents in TX now loathe him and his former conservative financial backers have utterly rejected him.
In all likelihood he is going to loose his reelection bid as a direct result of his own statements and actions. As for DT nominating him to the Supreme Court, that's questionable. Donald Trump has a long memory when it comes to people who intentionally treat him as badly as Ted Cruz has. However, DT is the premier "negotiator" and if he believes, after a thorough vetting process that Ted Cruz's nomination to the Supreme Courthe would ultimately be in the country's best interest I believe he is the big enough man to put his personal feelings aside and nominate him.
