Don’t get carried away. These primary polls with more than a dozen candidates are mostly meaningless.
Here’s the reality:
“Trump, Bush, Walker and Rubio are all viewed more positively than negatively, BUT TRUMP HAS THE HIGHEST UNFAVORABLE RATINGS. His ratings among registered voters overall are especially negative.”

So what that tells me is that Trump’s stances on the issues are a winner, but people don’t like Trump personally.
Those are the people who will eventually gravitate towards Cruz.
