I get why Rees Mogg gets the attention on this. He's the only politician I can remember who has been upfront and straight forward about his anti abortion views.
I'm just not really sure why that is given the weight it is. He's a backbench MP, and while he has quite an internet following and is a character, I don't get the impression he is all that popular among the powerful on his party.
If I were pro choice, I'd probably be more concerned by people who weren't as open about their views and were in a position of significant power, like leader of the party or something. Tbh, I think this is why Tim Farron got the clobbering he did, because he wasn't at all honesty about his personal views and that is rather a shifty trait in a politician.
