I will not be a Democrat or a Republican. They are the problem, not the solution. We need to abolish political parties in this country.

A bag of quality marijuana in Minnesota will cost you 400 bucks, in Colorado it'll cost you 100 and a quarter. Medical Marijuana, a pill that you've got to pay for - which, it's allowed in Minnesota, but it's so restricted - costs $600 a month. If you live in Colorado you can get the same medical marijuana for $30 a month. See why it needs to be legalized across the board?

I have an idea about voting, how about on every ballot we include "None of the above". People may laugh at that, but what that is, it is a vote of no confidence in your government and I'm willing to bet that in some elections, 'None of the Above' would win. Imagine if you won the election but lost to 'None of the Above'. Wouldn't that make you re-think your positions?
