While it is clear that the GOP is struggling, it is not fair to say that they haven't competed on the West Coast or in the Northeast. They are obviously second-tier parties in both regions, but have competed in Oregon out west and have been elected state-wide in New Hampshire and Massachusetts out east.
Fair enough, if you are talking about electing Governors and Congressmen, but with regards to Presidential elections it is a fair statement that with rare exceptions (Alaska and 1 win in the last 6 tries in New Hampshire), the GOP has not been competitive in the Northeast and the Pacific coast for over 20 years.
