While the man seems to be very strong on Catholic morals, and he would be far preferable to any other politician out there, I do suspect that his inclinations toward the Tridentine Mass may be simply a function of his overall foppish tendencies ... so, as someone else said, a smells and bells man.
Smell-and-bells is right.
Rees-Mogg wouldn't end abortion were he to become PM. He's on record stating that abortion law will not change. He's the type typical in right-wing politics who conveniently separate what they claim are their personal beliefs from public policy when it comes to anything which would jeopardize the social engineering of Jews.
This isn't to say people shouldn't vote for Jew-chosen frauds. When it's the only game in town then you can vote for the Jew-chosen fraud who is more to your liking. I did vote for Trump, after all, knowing well before I did so that he's as much a tool of the Jews (if not a crypto) as the next guy.
