Whatever it is, it has to be big - REALLY big. Huge. “Live boy” big.
I’m not even sure that a Kenyan birth certificate is “big” enough.
Even the Bush 41 “bombshell” may not have been the undoing; a popular independent plus “read my lips - no new taxes” was plenty.
We’ll see soon enough.
And big enough that a compliant MSM can't bury it.
If it just rattles around in the blogosphere for a few days, it won't have any effect.
