I believe this is correct.
By April (and maybe sooner) it will be down to 3:
Trump
Cruz
Bush
I think you are probably right samtheman. That being the case Cruz will have a great shot at the nomination. What most of the Trump people can’t see is that most primary voters are voting either for or against Trump. That being the case an argument can be made for about 65% of republicans being anti-trump. The more it narrows down, the more it help Cruz! In a Trump-Cruz head to head Cruz comes out on top about 8%. Not my words, but several polls. The sooner most get out the better!
