Tonight's election coverage

George Bernard Shaw died too early to enjoy the fruits of 24-hour TV news channels, but his famous condemnation of newspaper journalism would apply: "Newspapers are unable, seemingly, to discriminate between a bicycle accident and the collapse of civilisation."

While you're wincing at the usual cacophony, click over to Slate's interactive delegate counter and see for yourself whether it's possible in the remaining primaries for Hillary Clinton to catch up with Barack Obama. Nicely done.
