That may or may not be fair, but it does have one consequence: it makes it easier for Tory Remainers to vote LibDem tactically if situation demands it.
(They won't vote tactically for Labour.)
LibDems can in theory win tactical votes from: Tory Remain, Labour, Greens and unaligned/undecideds.
When it comes to tactical voting, the LibDems are fishing in a *much* bigger pond!
Why? Because LDs are by far the widest funnel to attract voters in the last minute quiet of the polling booth.
