What are or what could be reasons that Jackie as the new majority whip is against Claire's sexual abuse bill?
edit: First time, it is directly revealedto to the viewer that Jackie is against it is in Season 2 Episode 10:
(Jackie) I can't cosponsor the bill in its current form.
(Claire) Almost every woman in the House supports this bill.
(Jackie) And I can't be one of them. [...] It's because I honestly don't believe in this approach. [...] You never asked my position. You assumed.
(Claire) I can't imagine what that position must be.
(Jackie) I've served in war zones[...]
In later episodes, Jackie phones directly into a tv show to attack Megan.
(I hope the questions is not too speculative, but it seems to me that between lines there are some reasons)
