No matter the proof, conspiracies prevail

No sooner had President Obama released his long-form birth certificate than Orly Taitz, leader of the movement that doubts President Obama was born in the United States, found reason to doubt it.
"A step in the right direction," she said, even though it was precisely the document that many "birthers" had been demanding. And then she argued that it was still subject to authentication. Donald Trump, bouffant, blond and politically inclined, likewise breezed past the evidence, pausing to take credit for forcing the release of the document before suggesting that Mr. Obama was hiding something else - bad grades in college.
To many, those who doubt Mr. Obama's citizenship are driven simply by racial prejudice; they are unwilling to allow that America's first black president could hold the office legitimately.
