THE GUARDIAN: With such volatile voters, all poll bets are off for a snap election

Description

A “cold snap” election is the talk of the town, with the Commons set to vote on Monday on Boris Johnson’s request for an early election on 12 December. If they grant him his wish – and at the moment it looks a big if – MPs of all parties will be taking the biggest gamble in modern political history.

Johnson hopes to capitalise on a resurgent polling position and his Brexit renegotiation. Yet both of these advantages are fragile. Pollsters are divided, with estimates of his lead ranging from three to 15 points. British Election Study researchers recently declared the electorate the most volatile in modern political history. Voters can turn quickly, as the last occupant of No 10 learned to her cost.
