The waiting continues. All the indications seem to be that there'll be no announcement of vote totals in Montana for around three hours yet - AP suggests 12 noon GMT as the earliest, and that's before any challenges or recounts - while Virginia will surely take much longer. So I'm bringing the all-night blogging to a close in favour of some sleep. (Even if I'm wrong and miss all the action, you won't: I'll be leaving you in the exceptionally capable hands of the rest of the GU team.) We end where we began, on a knife-edge, and yet look how much has changed: the Democrats significantly exceeded most expectations, securing much more than a wafer-thin majority in the House, and a clear majority of governorships. CQPolitics has a great detailed analysis of how things may change in Washington from here on out.
Thank you for all your comments and your emails, which came from the US and UK, China, Japan, New Zealand, Australia, France, Spain, and elsewhere: they (along with the caffeine) made all the difference. I haven't forgotten about the predictions contest announced at the beginning of last night. Once the results are final, I'll announce a winner. And the prize. I know, I know: you can hardly wait.
