How Donald Trump Helps — and Also Hurts — Jeb Bush

A commentary by Chuck Todd of NBC News says Donald Trump might help and hurt Jeb Bush. The commentary also written by Mark Murray and Carrie Dann says
for Jeb Bush, the Republican presidential race becoming all about Donald Trump has its positives. One, it freezes the rest of the field, sucking up oxygen from other candidates. Two, it provides Bush with a foil to campaign against. Jeb can say, "I'm Mr. Responsible Republican, and we can't allow the irresponsible ones take over our party." But the commentary also says rise of Trump has one big drawback for Jeb Bush- It further exposes the party's wounds on immigration. For expample, look at how Trump fired back at Bush's criticism. Trump says Bush doesn't understand anything about the border or border security. In fact, Jeb believes illegal immigrants who break our laws when they cross our border come out 'out of love.'"
