The team-minded mindset, in my mind, is the thing holding this country back the most. It's a very frustrating thing to see the elected officials on either side turning down ideas they can admit are good and positive and what their constituents want because it is against their party line.
When I was doing Obama canvassing during the campaign, one day was about encouraging people to early vote, to give them basic information about how it's done, and where and when early voting took place.
We were then told not to let any McCain supporters know about early voting because it needed to be an Obama advantage. It was sickening; I was very disappointed with the idea that Obama would win based on his policy and the strength of his character was rejected by his campaign team in the area. It felt very Republican to try to win an election by denying information to the other side. I obviously didn't stick to such a ridiculous GO TEAM policy and gave the information on voting to everyone, but I can guarantee that of the nine duos that day, ours is the only one that did so, and it's a huge problem to me.
