@georgeob1,
I think you are way misreading to this result. The difference between 60 senators and 59 senators is big (because of some coincidence of senate rules) and this loss was improbable and disheartening.
But come on now-- this isn't "us" vs "them" where Conservatives represent some homogeneous American public and Liberals are somehow alien usurpers.
Not that long ago Obama won the majority of American votes by promising liberal policies from immigration reform to health care. As president he has certainly not turned out any more liberal then the candidate who made all those promises.
Obama being too liberal is not the reason he for this result in liberal Massachusetts.
Of course, I don't mind that you all are taking this position.
If Democrats figure out that they need to run great campaigns, work hard and strongly present their case to voters without taking anything for granted-- well the loss of one Senate seat still hurts, but this would be a silver lining.
If Republicans decide that they should become angrier and louder while assuming that all Americans agree with them because they are right-- that is fine with me too.
