Honestly, it's hard to know if anyone can win in this environment. It's an issue that concerns me, but I sincerely believe that Cruz will perform better than Bush. I think people are underestimating Cruz and overestimating Bush.
Make no mistake, Bush seems like a very nice guy. I just don't think that it will be enough in 2016 to be a nice guy.
Cruz seems to outperform his rivals. As you point out, he isn't making the mistake of attacking his opponents. I like his chances against Hillary.
Cruz has just the right amount of Trump’s anger, without sounding like a schoolyard bully and an abusive, angry adult child.
Trump’s problem is not his stances.... wherever they are this week.
Trump’s problem is that the “little angry boy” act wears very thin very quickly.
