I agree with that.....but to answer the headlines question, the only person who can topple Trump is Trump probably - and if he does topple for whatever reason, it will probably play right into Cruz' hands. There are some areas where Cruz is very much more reliably conservative....and I don't see Cruz bringing them up - but if they come up for some other reason, it will be very interesting to see how this plays out.
The other thing is....will Trump attack Cruz like he did Carson - when Carson surge in the polls? If he does, I think that will play into Cruz' hands. IF he does......
I don’t think he will. He has had good words for Cruz and implied that he would select Cruz for VP if he were nominated.
Cruz is running a very good campaign and doesn’t seem to be making any major mistakes.
If the remaining non-viable candidates running would do the right think and drop I think we could create an overwhelming tide for Cruz, or for Trump. Unfortunately the moron Bush the Lesser will probably not do the right thing for the country and drop. At least Nixon did the right thing for the country and resigned but I don’t think Bush cares a bit about the country or the Constitution; just his corporate sponsors.
