Intermarriage way back when in the ancestral family tree would result in the stark harsh RIGID SAME similarity of a Dr. Laura A Sean of Hannity a Rush of Limbaugh and the dumb don cabal et al etcetera etcetera etcetera. Their blood lines may be all intertwined and their DNA all comingled way back in time which explains how they all sound alike think alike having the exact same obnoxious audacious "personalities". Quiet calm classy they aren't. LOUD LOUD LOUD they are. Runs in families.
