Will the GOP take the Senate in November?

But those Indies caucus with the Democrats.

Yes, of course.  I'm just saying that, technically, Mitch McConnell might have an argument for saying he is the actual majority leader.

Only he wouldn't have a working majority, while Reid would, so no argument. If it's 50-48-2, the only way McConnell becomes Majority Leader is if he convinces Manchin or King or Heitkamp to defect (which I highly doubt they would.)

As of right now, I'd say no. Yes, they'll probably pick up MT, SD, AR, WV and LA if it goes to a runoff (though Landrieu has survived a runoff before), but I think the strength of Democratic incumbents and/or weakness of Republican challengers in AK, NC, and IA will keep them in the Democratic column. I also think that Scott Brown, Terri Lynn Land, and Cory Gardner are highly overrated and don't really have much of a chance of winning.
