The bottom line is this:
On 5th July we shall either have a Tory government led by Rishi Sunak - likely to be overthrown in weeks by some far-right loon - or a Labour government led by Keir Starmer.
That's the choice. All else is vanity unless you live in a constituency where the LDs, Plaid, Green or SNP have a good chance of winning. (Reform BTW won't win an egg cup.)
If I am given a choice between eating a low-quality beefburger or a dog turd, I'll go with the beefburger. Now, of course, I'd much prefer fillet steak, or lobster, or even haddock and chips, but they're not on the menu and the next nearest restaurants are in France and Ireland.
That's just how it is. I am not saying it's great or anything like that. We have to be pragmatic.
