The republicans blamed Clinton 7 years into Bush's presidency.
20 years earlier, TV networks (there were 3 major ones, not dozens like now) gave Reagan prime time almost monthly to make his self-promoting speeches. The purpose was to help his popularity ratings. The circular excuse was, "His popularity ratings are supposedly high. The people want this. Therefore, we must do all we can to help his popularity ratings." Well, I changed that a little, but that's the gist, and you can see the insanity of the 80s.
Anyway, in EVERY SINGLE SPEECH he put down Carter. He would mention the "recovery" which was a putdown of Carter. (Jobs were far more plentiful under Carter than under Reagan. The "recovery" was only for rich people.) He would say, "America is back." (It was, but only for conservative ideologues.) He would select slanted statistics which made the Carter years look like the valley of the curve.
Actually when I say "he" did this, I should say his speechwriters did it. He was too dumb to do anything other than read speeches.
Carter, a religious idealist who really tries to practice Love Thy Neighbor, didn't say anything until 6 years in. Then I read a small blurb saying he was getting frustrated hearing this BS. For years I had waited for someone to speak up about Reagan's blaming Carter in every speech and I thought, finally, he's going to defend himself. It didn't happen, because immediately, the little wisecracks against Carter stopped in Reagan's primetime speeches that the networks gave him for free throughout his 8 years.
Nixon didn't do this. It was under Reagan that the institutionalized Republican gridlock, sarcasm, and us vs. them anti-big picture attitude started.
