Today is the big grass roots Tuesday in Minnesota. Most voters flock to the final elections, but once you've participated in the caucus system, it becomes very apparent what "grass roots" means. The organized votes cast at the caucus level can change an entire party platform, and everyone knows, the caucus votes determine who the rest of the nation will vote for at the presidential election.
If, like me, you've not lived in your current location long enough to know where your caucus meets, you can find the Minnesota locations at this web site. If you've never been to a caucus, you might be surprised at how small the group of decision makers really is.
