Simple...You just say..."Hitler was a socialist, pro-abortion, anti-Jew, anti-Christian, pro-gun control...so your fear should be the Democrat party who has a KKK member they call the "conscience of the Senate."
Let's see. Bush worked for Harriman; Averill Harriman the radical Democrat was named by FDR to be Ambassador to the USSR. So, were the powerful Harrimans better, worse, or more venal than the Bush family? Or could it be that the Bush family is really closet Democrat? Or the Harrimans closet Republicans? Or is the whole Prescott Bush argument bogus?
