Great points and agree with analysis.
I'm also pleased we won't get a hard left majority government as much as I am a hard right one. The majority are more centrist.
As flawed as FPTP is, there is still an advantage in preventing the UKIPs, Reform, and hard left factions from becoming kingmakers in a coalition government, which is what PR (a more representative voting system) could make possible, as well as more collapses.
We all saw it with the DUP..... giving agency and a free blackmail pass to gain all sorts of unfair financial and legislative gains to a small fringe party.
Your point is perennial, but the PR liberals turn a blind eye in the vain hope PR will get them 'in', if they can just get the labour and tory turkeys to vote for Christmas and change the system.
Starmer angers the hard left and the lard right, so I'm IN.
