Now this is pretty interesting.... The chart above shows the approval-disapproval ratings for President Carter and President Obama in February of their fourth year in office (1980 vs. 2012), based on the Gallup/USA Today Presidential Approval Tracker website
. Carter's approval was 55% in early February of 1980 vs. 46% for Obama in mid-February 2012, and Carter's disapproval was 36% vs. 48% for Obama. Carter's Approval-Disapproval spread was +19 compared to Obama's -2 point spread.
: In March of 1980, Carter's ratings tanked and by the end of the month he was at -12 Approval-Disapproval.
