Yikes, I can’t really think Bush support is somewhere in there with Trump. Maybe so.
And, you’re right, at 7% Cruz is going no where on that, right now, but a Trump exit would surely take care of that.
We would like to think so but I predict it won't happen. I have avoided commenting on Cruz until Trump came out of nowhere, but I have never felt he could generate the excitement in the general public that he has garnered here. Even if he could the GOPe would go into unprecedented attack mode against him.
Trump seems to be immune to their blather. We shall see I guess.
