Hardly a fair comparison. It's not like 90+% of white, male voters go Republican. The alienation meme is more like wishful thinking that the Reps may once again see a presidential majority.
I was considering how to phrase exactly what you just said... The only thing I would add is that the Pelosi brand of liberalism is pretty much what the Dems have to start to move away from. There is a place for liberalism in the nation...nbetter ot only because the GOP makes the alternative so repugnant but because people want better and the GOP is the party of 1950 when the nation wasn't better for a large segment of the population.
Again; as Obama said in 2008.
If you want to go forward, you put the car in D.
If you want to go backward, put the car in R.
It basically is that simple when you go into a voting booth (in national elections).
