True they could but where would that get you? Do you think Social Security would be as wildly popular as it is if it had not had bipartisan support? Democrats could have pushed that through with out bipartisan support.
Health care reform is something that has to occur as it affects us all. It's long term affectiveness, particularly where managing cost is concerned needs bipartisan support. I despair of the ideological divide but it needs to be bridged in some way of affect and implement this reform.
