Republican National Committee Chairman Reince Priebus -- with a name like that, you know he’s got to be good -- has asked Donald Trump to cool it on the immigration issue. But why should he? Trump is in his glory hogging center stage. Other candidates will press their own wedge issues to gain attention. Louisiana Governor Bobby Jindal has vowed to force certain “spineless” Republicans into discussing abortion. I doubt that was on Prince Rebus’s to-do list. Hmm, first let’s alienate Latino voters, and then we’ll raise an issue guaranteed to upset women voters. Yup, sounds like a winning strategy.
