This is a Ted Cruz ad which his polling must show will be effective in the constituency he wishes to reach. You can make your own judgement.

But let me add this. Trump has started down the path of doubting Cruz’s eligibility for the presidency since he was born in Canada of an American mother and a Cuban refugee dad, similar to Obama having been born of an American mother and a Kenyan dad, even though within America. Whatever else may have made Obama unfit to be president, it was not where he was born or who his parents were that mattered. John McCain, so far as that goes, was born in the Canal Zone of an American mother and father which also would not have disqualified him. Trump is already a loose cannon without obvious impulse control and not everyone’s first choice for President, even in a post-Obama era. If he wins on policy, that’s one thing, but if he tries this kind of shoddy nonsense, then he will have difficulty holding his constituency together since he will have alienated a substantial proportion of those whose support he will need.

I am now interested to see that Obama has joined in: Team Obama Joins Donald Trump’s Attack On Ted Cruz’s Citizenship. Is there now an Obama-Trump axis trying to defeat Ted Cruz? It’s getting as hard to follow as the battle lines in Syria.
