Jeb Bush will endorse Ted Cruz in the race for the Republican presidential nomination, political consultant Roger Stone predicted toon Tuesday."John Kasich is not going to give up after winning his home state, even though I think that ballot is tainted," Stone told host Steve Malzberg on Newsmax TV's "America Votes: 2016" in an interview. "I still don't believe the establishment is ready to roll over and concede that Donald Trump is going to win this nomination."Watchonand. Geton your cable system –He said that calls regarding the rules of the upcoming Republican National Convention in Cleveland in July "are very troubling."These convention rules are being consistently rigged against Trump," Stone added. "I don't think California will end up being winner-take-all as expected because of flaws in the language there, in the party rules."This new call of the convention has unbound a number of delegates that Trump rightfully won in primaries and caucuses."The establishment is not giving up on their efforts to take this nomination away from Trump and some kind of a contested convention."
