One analysis here, from an unabashedly liberal source: http://www.theatlantic.com/politics/...-rank-and-file
" So many on the right had predicted a Mitt Romney victory, or even a blowout -- Dick Morris, George Will, and Michael Barone all predicted the GOP would break 300 electoral votes. ......Conservatives were at a disadvantage because Romney supporters like Jennifer Rubin and Hugh Hewitt saw it as their duty to spin constantly for their favored candidate rather than being frank about his strengths and weaknesses.....Conservatives were at an information disadvantage because so many right-leaning outlets wasted time on stories the rest of America dismissed as nonsense....movement conservatives, who believe the [mainstream media] is more biased and less rigorous than their alternatives, have no way to explain how their trusted outlets got it wrong, while the New York Times got it right. Hint: The Times hired the most rigorous forecaster it could find."
I agree with Stevein MN - I'd like to see two functional parties, and then a system that truly respects third parties and allows them to participate. Maybe starting with third parties - really including them - would improve the two main parties.
