reagan 1980 he did way much better then expected.
Polling back then weren't as nearly as extensive and sophisticated as they are now, and I've never been able to find state pollings from 1980 so didn't know what the expectation of Reagan's electoral vote count was going into election day. He was leading by a few points before the only debate between him and Carter. Reagan won decisively, and his numbers surged, but the debate was just a week before the election, so the polling didn't fully capture that impact.
