You seem to have an image of what you think I believe, and you work very hard to fit my posts into your preconceptions...and then, of course you extrapolate from there.
I don't think this election was a traditional R vs. D election, like the big R wins of the past which you mention. The comparisons were always going to fail to be instructive of this election. To expect this election to turn out like the last ones, which were very different elections...and to draw conclusions from that (other than that this was a very different election) is foolish. Past elections were mostly traditional R vs. traditional D, with no D motivation, so large R victories. With high D motivation (but no crossovers), Trump still came out with a pretty good victory. Very different election, but it seems that Trump has (amazingly) not yet destroyed himself.
