Point number three is also known as the abusive husband defense. See, his wife makes him beat her.
For 30 years Republicans have carefully cobbled together this coalition, nourished them with the fell meats of rancid distrust and bootstrappilosophy. "Getting government off our backs," was a useful dog-whistle slogan against tax collectors for a welfare state. The base new what this meant to them--don't take my hard earned money and give to some lay-about colored.
But what it really meant to the boys who ran the store was giving private corporations free reign to rape, pillage and plunder. It was a win-win for Republicans.
Then something happened. The Fairness Doctrine, which kept some sort of harness on the media, was killed during the Clinton Administration. Deep pockets began purchasing radio stations all across the land, pockets friendly to Republicans, and the steady encephalitic drip, drip, drip of right-wing ideologues like Rush began to seep into the next generation.
And market success began to overtake electoral victory.
Stars and multimillionaires were created out of this vast right-wing media conglomeration, and its audience became a movement who demand absolute rigidity in not only abstract political philosophy, but also in policy itself.
The result was that any and all Democrats must be hated. If they agreed with any Republican policies, then the policy must be flawed. No compromise ever on anything--compromise is like "date rape."
The moderates have been pushed out of the Republican party by the purists, and heated primaries to decide who have the wing-nut bonafides results in a treasure trove of Democratic ads to run in the general election. This will concern the "mushy middle" the swing voters, that are so precious in deciding elections.
The teabaggers are now in control of the Republican party, and every candidate actively and gleefully seek their approval. But there are only so many angry white folks to go around, and not enough to be more than an impediment to progress.
And this will only make them angrier. Sigh.
