The UK has one MP for (roughly) every 92,000 people, or 68,000 electors. Oddly enough, the UK Parliament has hovered around the 600-650 mark since the 1820s and usually has some slight changes up or down when dictated. The biggest change was the elimination of University Seats and "double" seats, where two MPs would be elected for a single seat back in 1950.
Current proposals are to move to 100,000 people in every seat.
Strangely, polls are reporting his seat is on a knife edge. So it's exactly the kind of thing Lindsey needs to shove and energise his own base that little bit more.
Oh look, another one where they start playing the numbers game. They tried this bullshit in the UK too to try and delegitimize the Brexit Referendum. Mostly because "only" 16% of the population actually voted for Brexit and thus its totally not a majority opinion! No you're the minority here!
They tended to shut up when you point out by that logic absolutely no government ever would be valid because "the majority of people didn't vote for it". It's why we do shit on a turnout basis. It's why the US does things representationally because otherwise the whole union would be dictated by ruinous Californian policies that'd probably see Idaho and Wyoming perpetually on fire and New York wondering why their grocery stores wouldn't get restocked.
