It's definitely interesting that that's what she's doing at the moment. First, in more normal times you'd think that one of the bigger names in the Tory party would be at conference right now being hosted at posh dinners by various groups wanting to hang out with her.
Second, that she's taking her Toryism *so* seriously that she's taken the time herself to go door knocking in Tamworth. Nobody is making her go there. It would be perfectly easy for her to go and do a couple of lucrative speeches somewhere or just have a nice holiday for a couple of weeks. And Tamworth staying Tory for another twelve months makes literally no difference to her personally.
So while they're pretty terrible ideals she holds, you have to admire her commitment to them.
edit - scrap this, she's in Manchester. Cleared popped in to Tamworth on her way up.
