The GOP should have learned their lesson from nominating true moderate John McCain.
Moderate McCain had less to do with him losing than a failure of campaign strategy combined with hatred of Republicans because of Bush.
No, I'm pretty sure McCain's "moderate" mishandling of the financial crisis was what brought him down.
This. And hugging Bush. And continuing to take the same stance on foreign policy and then some as his predecessor. Actually come to think of it, if McCain campaigned more like Bush
in 2000 instead of doing a bad imitation of Bush in 2004 he would have done far better.
