Polls from last century wouldn’t have any meaning in this election. Now, if your a historian, I’d say try Google.
I’m not looking for polls, but party ID breakdowns. It would be helpful to look at the party ID breakdowns from that period since that was when the GOP was in their worst shape, until now. It would be nice to compare those party ID breakdowns and those polls to today’s.
Methinks you have (perhaps intentionally) missed the whole point.
The point: polls have been wrong for many election cycles. It suggests that the polls historically have maybe been misreported or twisted or whatever to show the democrat is winning. In 1978, for example, Minnesota Republicans won "unexpected" victories for US Senate and Governor. The Minneapolis (Red) Star had reported just prior to the election their polls indicated a democrat sweep. After the election they reported their polls had indicated the republicans would win, but "they didn't believe them". History can teach you things if you pay attention.
If your post included one of those invisible sarcasm tags, please excuse me for missing it.
