A liberal will say yes, because broccoli is good for you and health care is expensive.  It’s for the common good.

A conservative will say no, because it should be the consumer’s choice and government is growing too intrusive.

The average American who doesn’t follow politics will give an answer dependent upon whether or not they like broccoli.  If they like it, they’ll say, “Well, I like broccoli and it’s good for you.”  The concept of choice won’t register in their brain cells.  If they don’t like broccoli, they’ll shake their heads and mutter a little bit about damn politicians, but won’t know which party to blame.  Within a week, they’ll be buying the required amount of broccoli and will have forgotten the government mandated it.
