House Seats are still capable of being moved with a big influx of money. They are also helped by smart Mapping of Congressional Districts. That is still where Republicans have a better game in winning. That is why Norquist is all about the House.
Even a superstitious man has certain inalienable rights. He has a right to harbor and indulge his imbecilities as long as he pleases. . . He has a right to argue for them as eloquently as he can, in season and out of season. He has a right to teach them to his children. But certainly he has no right to be protected against the free criticism of those who do not hold them. He has no right to demand that they be treated as sacred. He has no right to preach them without challenge." -H.L. Mencken
