This new national poll shows a “massive 20 point drop” for Trump in GOP voters believing he will be the eventual nominee.
And a win in NH will change that. Look, a poll is just a snapshot of the now. It is not a prediction of future. Trump is ahead in NH now. By tonight he may win by 2. Cruz fit Iowa. Trump fits NH. Rubio will fit SC. And on we go for several months.
If they conduct the same poll tomorrow it will show a 20 point surge in same. If Trump's lead with likely voters doesn't start dropping soon Cruz is hosed.
