This morning’s YouGov poll for the Sun had topline figures of CON 31%, LAB 44%, LDEM 12%, UKIP 9%. The twelve percent support for the Liberal Democrats is the highest that YouGov have shown since way back in April 2011. All the usual caveats apply about unusual poll findings apply – more often than not they are just blips – however this is part of a wider pattern in recent YouGov polling, that has shown the Lib Dems sneaking up into double figures on an increasingly regular basis. Eight out of nine YouGov polls in December have shown the Lib Dems at 10 or above, compare that to 5/21 polls in November and 5/23 in October.
If is it sustained it will be worth looking at exactly where the support is coming from and trying to work out what is driving it, but the Lib Dems have been increasingly differentiating themselves from the Conservatives over recent months – that would certainly be a potential cause worth looking at.
