A vendetta (blood feud) against PDJT by 0bama began when Trump raised the issue of 0bama's missing birth certificate as a guest on The View in March, 2011. Stung by Trumps questions, one month later 0bama published a demonstrably forged BC.
Exposure of the fake birth certificate threatens 0bama like nothing else. Can you imagine the horror and disbelief in 0bama when Trump (his most prominent birth certificate skeptic) became President and now has the power to lay bare 0bamas many lies?
This IMO was the single most compelling reason that 0bama joined (if not led) the Steele Dossier insurance policy coup.
The swamp will never be fully drained until all of 0bamas many lies about who he really is are brought to light.
Exactly right.
