It concerns the bill HF495, which was passed in committee but has yet to reach the House floor. It is considered likely to pass. The bill will give all of Minnesota's electoral votes in presidential elections to the candidate who got the most popular votes nationwide.
I believe this bill seeks to take away the power of Minnesotan's votes by giving them to whomever the rest of the country voted for, no matter how Minnesotan's really voted. It's a sneaky way to circumvent the true intent of the electoral college.
Anyway, Sheila writes it much more thoroughly on her blog, so visit the article, and contact your legislators immediately to tell them to vote against this bill. The legislative session is about to end, so don't wait!
