You had to see this coming. Enduring two weeks of excruciating humiliation has put a major dent in Donald Trump's "presidential campaign" (probably also his in ego). First, his base of support--birthers--has been cut in half following the release of Obama's birth certificate, per a new Washington Post/ABC poll. Last April, 20 percent of Americans thought Obama was born abroad; now the people who believe that--call them "after-birthers"--are down to 10 percent. A couple weeks ago, Trump had stormed to the top of the GOP field. This morning, a Suffolk University poll of New Hampshire voters has him drawing a measly 8 percent. He's so toxic that the Indianapolis 500 has decided not to let him drive the pace car this year. But there has to be a silver lining. As several people have noted, Obama cut into Sunday night's episode of "Celebrity Apprentice" to announce that Osama bin Laden had been killed. That drew the biggest TV audience ever for an Obama speech. So surely Trump, whose ratings have plummeted since during his campaign, got a nice little ratings spike as a result, right? Wrong. I checked with the Nielsen folks. His ratings were flat.
