Partisan Polarization Surges in Bush, Obama Years

[freepcrusher]

my opinion is that it accelerated in the 1990s where it became frighteningly apparent that people in both parties were creating there own echo chambers. The conservatives were moving to areas such as the districts of Dick Armey, Joel Hefley, Newt Gingrich, Tom DeLay etc to create their own echo chamber while the liberals tended to congregate in areas such as Manhattan, the lakefront wards of Chicago and San Mateo County CA.
