Why Not Trump?

The latest political fad is Donald Trump. Both conservatives and liberals despise him, so obviously, he is doing something right.
Trumps was in Las Vegas yesterday and spoke at the Trump Towers. Even though the national media said the Trump Tower in Vegas has a casino in it, it does not.
Let's start with this; The Trump Tower in Las Vegas. It was not built with government funds nor was it built with government union workers. It was built with union workers, like iron and electrical workers and plumbers and a lot more employees. He continues to provide employment for at least a hundred people in Las Vegas.
How many people does Obama employ in Las Vegas. Obama just tells people not to come to Las Vegas and spend their hard earned money.
How many people has Donald Trump employed and continue to employ? How much health insurance do his companies buy?
How many people has Obama employed in his life? (government employees don't count) how much health insurance has Obama paid for from his companies?
Who has more experience in how the world operates? A businessman or an community organizer?
Who would Red China, Pakistan, Afghanistan, Iran listen to better? Obama or Trump?
Who understands the business world better? Who knows customer service better? A community organizer or Trump?
I'm not sold on a Trump candidacy but considering the GOP presidential is really weak so far and Obama is going to be very vulnerable in 2012, so why not Trump?
