Obama was right...the more people understand and begin to benefit from the plan, the more they will support it. The biggest complaint has been that everyone must carry health insurance. Well, this has been a stipulation in Massachusettes for some time under conservative Mitt Romney's plan. You can't have an insurance plan where people only choose to participate when they become ill or injured. No insurance works that way.
And the "if it's so great, why doesn't congress use it?" argument is wearing thin. People are beginning to understand that you don't HAVE to take the national health insurance if you already have something better. The electorate is pretty ignorant and vulnerable to scare tactics, but time and participation will eliminate that.
