The GOP got 47.1% of the vote in 2012. McCain got 45.7% in the worst possible conditions for a Republican and with a complete and widely mocked idiot as his running mate. I'd call that a national party.
With the way many Democrats talk, you'd think Republicans can't crack double digits.
It's pretty telling and/or significant when a party derives 41% of votes cast for its nominee, 46% of House seats & 47% of Senate seats from a region that only comprises 37% of the country (my map above; unless you're the majority party, of course).
But hey, Romney only got 28% of his campaign contributions from here, so that's a start.
