Could it be months, years or even more than a decade?
Exactly a year ago we ran a competition here asking when entrants thought that the Conservatives would regain their poll lead over Labour. The thread makes an interesting read.
At the time the Tory deficit ranged from 3% to 9% (the biggest coming from YouGov) and it took the party just two months to restore the situation.
The current Labour deficits are reproduced above and the question now is how long will the party have to wait? In our online survey I am asking you to vote on the year when you think that at least two of the pollsters that carry out monthly surveys will be showing Labour back in the lead in their latest polls.
Could it happen this year or next if a new leader gives the party a bounce? Could Labour have to wait until the Tories are experiencing the normal mid-term problems? Could it be decades?
Clearly the pollsters can change so the firms in this online poll are those that carry out monthly surveys for publication.
