That's not what their electorate looks like now, it's what it
used to look like between the Iraq War the tuition fee betrayal.
After the election of Corbyn, who wants LD diet that's left a bad taste in your mouth when you can have full fat Labour? Yes Corbyn's Brexit ambivalence is an issue but on many other aspects of politics he sounds more on their level.
With leaders of both parties being pro brexit (At this point) you would think the Liberal Dems would poll much better
FPTP means you need to pick the party closest to your views
that also has the best chance of winning. Even though Corbyn is ambivalent about Brexit, the Labour party itself has an overwhelmingly Remain demographic of urban and affluent voters.
For what it's worth May is not "pro-Brexit", she's a Remainer who can't even bring herself to say she thinks leaving is a good idea. Leavers don't trust her, they simply have no choice but to stick with the Tories until they get it through. Same with Remainers, they aren't necessarily happy with Corbyn but they feel Labour are in a better position to get some "wins" for them.
Besides, there's more to politics than Brexit....
