Hillary beats Trump by TEN POINTS.
Cruz beats Hillary.
If Cruz manages to get to a contested convention and isn't betrayed by those he thinks are supporting him (they really just hate Trump more because he's the true anti-establishment guy in all this), I hope you are right.
I find it ironic that those who originally came out so strong against Cruz as "too radical" are now in full anti-Trump mode and not saying anything bad about Cruz - they fear Trump more and are waiting to see if he can be stopped so they can concentrate on Cruz who the also detest.
So many polls out there it's hard to pick which are correct, what the actual wording is, and what the makeup of those polled is. When citing them, one should also look at other than the final numbers as a reality check. There's also a lot that can happen between now and then, not to mention when the choice becomes absolute due to someone else not being available in folks minds - just as many will vote Cruz if Trump drops, others will vote Trump is Cruz drops - the availability of one or the other changes the dynamics of those responding to the polls.
