We are overlooking the fact here that Donald Trump is a master marketer - he is genius at playing the game.
If Trump would have talked about the debt crisis he would 1) gone unnoticed and 2) asked to present his plan. The same concept applies to any of our foreign wars, or Israel, etc. These issues do not attract the press and the attention. People are saturated with these important but thoroughly discussed, and boring issues.
Knowing this, Trump comes out with a vengeance on the "birther" issue (is that a real word?). It is a win-win situation for him. He grabs the attention of something that lingers in the back of people's mind; plus, he doesn't need to come up with a solution to the problem.
It got almost as much press as the royal wedding
, and pushed him to the top of some polls. I will bet in the near term he will keep with that strategy. All the politicos will call him silly or racist - a claim that doesn't stick because issues like these do linger in the back of many people's minds. Plus, it is fresh and new. Next Obama's grades and China (the country we all love to hate).
He is using masterful marketing techniques to stay in the news. "I don't care what you call me, just make sure you put it on the front page of the news." Could be a winning strategy.
