They fear her most because sh represents an existential threat to all they have been building in this country (or should I say, tearing down in this country) for the last 50 years.
She is preparing to kick the hell out of them. They see it and are panic stricken, as is the GOP Establishment. why do they fear her? Simple: Why does baloney reject the grinder?
THEY FEAR HER BECAUSE SHE DOES NOT FEAR THEM!
THEY FEAR HER BECAUSE THEY ARE TERRORISTS
AND FEAR IS THEIR ONLY WEAPON.
THEY FEAR HER BECAUSE THEY FEAR US
AND SARAH IS US.
