This shows the current size and time weighted average of all the public polls.
Labour have been in the 20s in the last seven polls. The last two polls had them at 23.5% and 24.9%. The average of all polls has them polling below what they got in 2011. By comparison in Sep 2011 they were polling at 32.5% so they are now polling 7% lower than at the same stage of 2011.
This is no reason to be complacent, as National always drops away when in Government during an election campaign. However it is hard to see how Labour can credibly form a Government if they get a result in the 20s, even if it becomes mathematically possible.
Just 65 days to go until the election.
