The GOPee is working to accomplish the same split.
Trump helps their goal of splitting the conservative vote for Jeb, problem is Trump is leading Jeb in the polls.
Perot was in to help Bill Clinton in 1992 and when he led the three way general election race, Perot announced he was pulling out and said weird things deliberately.
Then Perot came back in once his numbers were low enough to help Bill Clinton win the 1992 race. Perot was back in 1996 to help again.
MY SENSE OF THE SITUATION AT THIS MOMENT IS THAT THE GOP ESTABLISHMENT IS DESPERATE ENOUGH TO PULL TRUMP DOWN THAT THEY ARE PUFFING TED CRUZ UP.
