The major change in the past 10 years has been the affective disposition towards the opposing party. People now hate the opposing party.

During the Carter administration, cross-party ratings were not much below 5o — just slightly cool. But Democrats’ ratings of Republicans go steadily down from there, falling to 33 degrees under George W. Bush and a frigid 17 under Barack Obama. The Republicans show a slightly different trajectory, holding steady during the twelve-year Reagan-Bush period. But beginning with the Clinton years, Republicans sour on Democrats and join them in intensifying mutual dislike (18 degrees) during the Obama administration. To put those low scores in perspective, they are even lower than Democrats’ ratings of Richard Nixon in the years after Watergate.
