The United States is a democracy.They'll spit and sputter in rage. The more educated among them might try quoting Alexander Hamilton and say that the Founding Fathers hated democracy and considered it akin to anarchy. Others will point to the Pledge of Allegiance as absolute proof that the United States is a republic and not a democracy (ignoring the simple fact that the meter of the poem, written in 1892, required a three syllable word).
The ignorant Tea Partier will simply yell "Democracy is evil and contrary to God's law." Then there is the batshit insane Tea Partier who will tell you that democracy is a Jewish conspiracy of the Trilateral Commission being used to turn the United States into a fascist/communist dictatorship.
Pruning away the rambling verbiage, their principle difficulty with democracy is universal suffrage. Their preferred form of government, think Roman Republic, is one where only the most deserving have the privileged of voting. They want the 17th Amendment repealed ("It made the Senate more democratic — and that’s not good") because they believe the direct election of senators was a horrible decision and that senators should be appointed, as was done in Rome, without public input.
The new Jim Crow voting restrictions are just the beginning of the ultimate goal. Disenfranchising African-Americans, the disabled, Hispanics, students, even women and the elderly is an intermediate step. Their ideal form of a republic will restrict the voting privilege to taxpayers ("Universal suffrage is immoral"). With that simple change, Mitt Romney wins in a landslide.
Tea Party Republicans believe that democracy is "mob rule." Their mantra is "Voting is a privilege, not a right" and a privilege that only a select minority, the "select" being, of course, themselves, should be allowed to exercise. If only they can keep the common rabble, the hoi-polloi, hysterical females, and coloreds from voting then they will final deliver the nation from the curse of evil democracy.
