I've long had a theory that the GOP and the neolib Dems benefit from the fact that GOP voters, for the most part, can get their moral rocks off voting against the gov. in the confidence that what they will receive is a bit of a tax break - and continued service from the Gov, since the opposition Dems will see to that. Thus, Social Security and Medicare are safe. That was not a bad strategy for GOP voters - and Trump seemed to reaffirm it when he promised the continued service from the Gov. Now the shit is coming down, and the Dems are finally weak enough that the GOP can do what it wants without any check or balance. In consequence, you can superimpose, over those maps showing the Red counties - which were in rural or exurban areas of the country - another map, showing where the burden of cuts are going to fall. Guess what? The bleeding will start with them. The strategy doesn't work if there is too much GOP-ery - then the moral stance agin the Guvmint becomes a practical sink or swim deal.
When I use the word strategy, here, I should make it clear that it is a strategy the way natural selection is a strategy - it is not the intention of the voters individually, but the environing pattern they react to and shape as a group,
So why didn't the Dems pick on this in 2016? a recent Vox article about HRC's ads, to which a major portion of campaign funds were allotted, tells the sad tale. HRC ran on a platform that was full of incredibly popular programs. She could have trounced Trump in every policy category. But her campaign team thought they were on the Apprentice set, and didn't go with icky policy stuff. Cause who really cares if you can afford childcare or healthcare? This is still echoed in the pundit chamber with remarks about how dumb your average American is. Cause we are all for democracy, we who went to the Ivies, but come on! Those dummies always need our nudgin'.
