Per this morning's post, I just voted.  This was my favorite overall, and I have supported the idea in the past:

 

Do not tie healthcare to employment:

Job-based healthcare insurance is very bad for our economy for two main reasons. First, job-based healthcare drives up the cost of American products because corporations have to pay costly healthcare premiums, making it very difficult for us to compete globally. Other countries have national healthcare insurance, so their product costs are lower. Secondly, job-based healthcare insurance restricts the innovative spirit of the American people. Our workers stay in jobs they don't like rather than making career changes or starting their own businesses because they are afraid to live without healthcare insurance.

We need national healtcare insurance, and I propose that we fund the program with a special sales tax so that EVERYONE pays into the system at least a little bit.

If we have national healthcare insurance, the cost of American products would go down and large companies could expand into global markets. We could keep jobs at home. Also, our workers would have job mobility, which would make our existing companies better and also create a safety net for new entrepreneurs

I am not sure how I feel about funding it with a sales tax...those taxes tend to hurt the poor more, and are essentially regressive in that the poor end up paying a greater overall percentage of their income in sales tax than the rich (not in every case, of course, but often).  Also, the concept of a FEDERAL sales tax would inflame a huge portion of the right, and kill the plan.  The best option would be some sort of tax on large employers (greater than 500 employees) of a very small percentage.
