How so?
Which comment are you referring to?
Gabbard or Sanders as VP? Both help Trump, Gabbard the most--former Dem like Trump, an Independent, views are moderate like Trump, woman, person of color, attractive, which helps with Trump, and a veteran. Checks off a lot of boxes.
President Trump as Florida resident and too late to change? Yes, I think so, since he has filed paperwork to run for President as a resident of Florida. Not sure if he can change. A VP, just nominated and not filed, like Cheney years ago, can change.
