The reason Clinton pushes the birther issue is her focus is on the identity of her predecessor - the first Affirmative Action President.
It was said previously Affirmative Action (AA) Civil Rights agitation can get you so far but not to the top. Obama showed us yes you can.
Clinton’s defense of Obama’s identity is an implied defense of the Affirmative Action campaign of the LBJ/Civil Rights anti-white-man left.
LBJ AA/CR is a zero-sum game contest between every identity and the white man to subvert him and overturn history (for a leftist worldview).
Obama said ‘yes [we] can’ overthrow the white man and Hillary Clinton implicitly states as well: ‘yes [I] can’ do the same.
Obama has spent 8 years arrogating land to the federal gov, fleecing pvt sector & waging war by stealth v Israel’s foes (all)
Obama has spent our money on paramilitary accoutrements for a complement of romanticized jihad at the feet of OPEC/UN/Israel
He has distracted us from merc warlordism via inner city agitprop to stir dissention v traditional civil protection (police)
