Many people, some of them here have talked about how the republican party will become a permanent minority. This will never happen.
Yes, the republicans are are on the long term losing side of some issues, marriage equality comes to mind. And the republicans are changing their position on those issues, Mark Kirk just flipped to supporting marriage equality despite not having gay children.
But the argument as to why the republicans should get used to the minority often boils down to the notion that they have policies that are far too extreme. While true, this doesn’t mean that they can’t win elections. Voters to a first approximation don’t care about policy details. Furthermore only about 10% of voters are swing voters anyway. So all you can promote terrible policies all day long if you avoid saying blatantly offensive things, in other words, you can promote hurting poor people every year (hello Mr, Ryan) so long as you avoid saying things such as “legitimate rape” in which case the electoral body has ways to shut the whole candidacy down.
Let me close by reminding you my fine readers of Karl Rove not a decade ago talking about a permanent majority for republicans. You can ask him how that worked out or better yet ask President Obama.
