Or if he is going to have the opposite effect and make them look reasonable by comparison.  

I do have to agree with bird brain that the more important thing the GOP has to worry about letting another Todd Akin run amok without being able to shut him down. Or even worse pandering to the social conservatives and making the race about issues like Gay Marriage and "Right to Life" If that turns out to be the case, they might as well have Hillary's coronation right now and spare us a year of listening to campaign ads.

OTOH, if someone like Jeb Bush can run a positive campaign, while letting the PAC go negative against Hillary and all her baggage, that could even the race from a strategic point of view and he can "out charisma" her and actually win the election with a lot of Hispanic support. (a "lot" being defined as anything over 40% in this case) Not taking party bias into account, Jeb Bush relates to Hispanics a thousand times better than Hillary, and he does it effortlessly, none of it seems even the least bit forced, unlike when Hillary tries to do it
