The idea is to keep the anti GOPe vote unified unlike previous elections. Obviously, Cruz is the superior candidate, but Trump has been more effective at generating publicity and getting under the skin of the establishment on both sides. OTOH, Rand Paul has been politically very foolish to criticize Trump especially when Paul is also an anti GOPe candidate.
I’m a Cruz supporter, but I don’t mind Trump attacking the GOPe and the establishment in general. Marginalizing jebbush and his sycophants like George III Will is what we need at this early stage.
Using what metrics?
yup you nailed it
