Here's how I think it's supposed to work.
People are turning away from the GOP in droves, and probably, while a lot of them intend not to vote at all, a nice big bunch (who would usually vote for them) intend to vote against the Repubs like they did in '92. If you can keep a significant percentage of them from voting at all, you'll probably still lose, but it'll look really close, and that's what matters now.
And even if you can't keep enough people away from the polls to make a big difference in National or State-Wide races, you can prevent the balance being tipped in the very important "small stuff" races like County Supervisor and DA and State Legislature etc. So if the GOP can keep a handle on that level, then they can go on pretending they have a case to make about "big, far-away government tellin' the little guys what to do yada yada yada".
Remember always that elections get decided by about a dozen votes per precinct.
The key is maintaining balance between the 2 competing sides. If the Red Group has 49%, and the Blue Group has 49%, that means I can throw in my 2% to support whatever candidate promises me the biggest tax breaks or subsidies or military protection for my investment holdings in FuckedUp-istan, or whatever. This is the old game of Divide And Conquer, but with a heapin' helpin' of Henry Kravitz Corporate Raider thrown in.
(And don't you dare start thinking we aren't being distracted while certain politicians are working hard to sell everything in this country to the highest bidder and take us back to the glory days of 1750, but that's a slightly different rant - closely related, but that comes after a few more rounds)
Voter Suppression is all about not allowing "the divide" to get so big that the 2% loses its oomph.
But also too, remember that the GOP is very much on the defensive:
1) makes it all the more dangerous
2) they're just looking to survive to fight another day, and that means:
3) the Dems have to dominate. They have to win big. And when was the last time they managed that one - and more to the point of my theme here, when was the last time they were allowed to do that? Hillary seems to be the perfect fit for the occasion - ie: she'll win, but not by enough to upset that delicate and finely-crafted balance. And that also is a slightly different rant.
And BTW - if you think it looks like a mini-series on network TV, you ain't wrong. The game is totally reliant on distraction and misdirection, and we've been thoroughly conditioned to get caught up in the gripping drama of real-life events as they unfold blah blah blah, so that we stay frozen in place, allowing "our betters" to make the important decisions for us while we pretend to be well-informed and involved.
One last wrinkle: those astoundingly shitty Anti-Civil-Rights laws passed recently in Georgia and North Carolina? That's this year's version of The Big Wedge designed to motivate the "Christian Values Voters". The GOP will likely flack the fuck outa that one, screeching that the valiant "conservatives" are trying to protect Real America from The Homo, and if you don't go vote, then the police will have no choice but to break down your doors and force you to Gay Rape your house pets. You know the drill.
Up on your hind legs, kids. Stay together. Work together. Get shit done.
