To me, as a Norwegian, the thought of feeling so tied/connected/whatever to a political party that you essentially hand them your vote no matter what, for life, is very strange. I've voted for what must be 6 or 7 different parties, so far in my life. My vote goes to the party whose policies most closely align with my own thoughts (at the time) on how and what to address, and the people I feel are most likely to follow through on their promises.
