Incredibly, Sen. Marco Rubio, he of the crude, schoolyard taunts of Trump, has blamed this repugnant and dysfunctional political culture on the nation's leader. Rubio has claimed, "There's no doubt" the president shared responsibility for the nasty rhetoric and violence that is playing out this campaign season. When asked how in the world this could be so, Rubio had to reach back five years to an April 2011 speech when Obama criticized the GOP budget proposal for threatening to change "the basic social compact in America." This proposal cut funds for Pell grants for college students; called for the eventual elimination of home buyer subsidies from Fannie Mae and Freddie Mac; repealed the Affordable Care Act; slashed Medicaid; and privatized Medicare. Well Marco, if it walks like a duck, quacks like a duck, and looks like a duck, there's no need to consult an ornithologist.
