"Well, the Republicans have all but conceded one of those races, meaning Democrats only have to win 14 more."

Sounds good. But "all but conceded" is light-years away from "have conceded." Democrats still have to win 15 races to take back the House. It's nice to know that this one might not be as fiercely contested as some of the others are, but that doesn't mean the D's That Be can relax and let their hair down on this one. There's no margin for error, not this year, and no room for slacking off. The slimness-challenged Valkyrie has yet to perform her final aria over any of the 15, and this one ain't over yet by a long shot.
