They'd never say it publicly. But catch many Democrats in an honest moment and they would admit that a Republican-led government shut down this fall might be the best thing — perhaps the only thing — that could revive their fading hopes of capturing the House next year.
As it stands now, the midterm is shaping up as a stale, status-quo election — with Democrats calling their counterparts right-wing extremists, Republicans attacking their rivals over Obamacare and neither side making much headway. That's good for Republicans, since the party out of power in the White House almost inevitably picks up House seats in the sixth year of the presidency. Heavily-gerrymandered districts provide the GOP an extra layer of protection.
