Philosophy on tossups?

[jerusalemcar5]

I put tossup on many of the close races because I don't want to be blindly partisan.  I recognize the race will be close, but I think that the Democrats can pull it out in many of the races because of the political climate.  To me, lean means I'm 50% confident since it's the middle of the three choices.  I don't think that I'm 50% confident for many races.
