In the current presidential election, this is the only thing that really matters — the breakdown of the Electoral College and who's gonna hit 270. That's a link to the Cook Political Report, which is a non-partisan entity. That of course means it's non-partisan to most folks when it tells them what they want to hear and it's deeply, undeniably biased when it doesn't.
I'm just dumb enough to believe that it's honest even when it doesn't tell me what I want to hear. Of course, one must remember that it's 186 days until the election, we don't yet know who the running mates may be, what anyone will say in their next five hundred speeches or at the conventions, what new issues or scandals will erupt, etc. Right now, it looks very good for Democrats, not so good for the Republicans. If this was a normal election, I would say it's all over but we don't have normal elections in this country anymore.
