So the Lib Dems are optimistic about their chances on June 8th. All 48 seats they lost in 2015 will be “in play”, reckons Rob Ford of the University of Manchester. A 10% swing to the Lib Dems would see them pick up 40 seats, 25 of them from the Conservatives. They are unlikely to do quite that well—partly because eight of those seats are held by the Scottish National Party, whose vote is likely to hold up, and partly because the Liberals’ organisation is still relatively weak after successive local electoral drubbings. But Lib Dem watchers guess the party could pick up more than 20 new seats. Popular former MPs including Vince Cable, a former business secretary, and Simon Hughes, a former justice minister, have said they will seek to win back their old constituencies. Nick Clegg, a former party leader and deputy prime minister, has confirmed he will stand again.
