Holy, I get that things are bleak to say the least, however the GOP is doing this because they're looking at heavy losses across the board, not just in VA. I think you're missing the whole picture to be honest. Plus, gerrymandering can backfire as you're diluting the voting pool. I understand dooming and all, but I think it's too soon to say that the Dems will certainly lose the house.
That's not to say this isn't a bad thing, but it also could backfire and cause higher turnout.
They just want to be right, that's all it comes down to. They do this a lot around here, they simply refuse to consider anything but their own opinion, so when someone challenges that, they lose their mind and thus their reading comprehension. They also love to twist your words to make it seem like you're the one that doesn't understand (as they've done to several people, including myself, in this thread).
