I think he is, therefore he is:
INDIANAPOLIS—Unless citizens throughout America keep him in their thoughts, say his name to themselves over and over, and otherwise believe in him with all their might, Barack Obama may cease to exist, the candidate warned supporters Thursday.
"My fellow Americans, I am currently very strong and very, very real," Sen. Obama told a cheering crowd of 12,000 at the Indiana State Fairgrounds. "Even here in Hoosier country, a traditional Republican stronghold, your faith has kept me from growing faint, becoming transparent, and slowly fading from view."
"But please, don't stop now," Obama added. "Unless you continue to believe in me, I'll completely disappear. You have to keep me in your thoughts at all times!"
Thank goodness for The Onion -- it may be our only comic relief for the next four years, since everybody else seems afraid to make fun of Obama.
