There’s always been something just a little off about Alan Keyes, but his latest obsession plants him firmly at the head of the tinfoil hat brigade:

The controversy over the validity of Barack Obama’s birth certificate is back on a burner with firebrand conservative Alan Keyes making serious new charges.
