Most of the ridiculously pro-EU people who consider reversing Brexit to be their primary priority were most likely part of the LibDem base to begin with. They'll attempt to draw in more Remainers and in doing that they will interpret an increase in the vote for them as a show of support for their position on the EU, but @I_am_the_Senate doesn't care about that narrative because it's highly unlikely that they're going to surge or be in a position where they could help form a government. I'm also pretty sure he lives in a pretty strong Tory safe seat, though I may be wrong.
In my university constituency, the Conservatives were fourth place in the last election. Labour were first, Greens second and LibDems third. Labour won the seat off of the LibDems too. Safe to say that any vote for the Conservatives here probably isn't going to do much unless there's an absolutely amazing night for the Conservatives that tops even Blair's 1997 landslide.
