I definitely like Carly as Cruz’ V.P. She is perfect to be the Hillary attack dog and really outshone all the other candidates in doing that in the primary. She might not be a reliably conservative president, but she probably wouldn’t be handed an automatic primary win in 2024. She’s enough of an outsider to not make it look like Cruz is selling out to the establishment, but she doesn’t look unqualified or risky like Palin did. Her outsourcing record she got hit with in California just wouldn’t be able to bubble up to a major issue when she’s only the V.P. pick.
It'd be a good opportunity for either Trump or Cruz to change the media-driven narrative about their campaigns. Having a tough, capable woman who isn't a crook firing alongside them may be something that sets Hillary back a bit.
