There is no political figure that is serious about our border with mexico. The real goal is to have mexico and the US become one, and i wouldn't be shocked if meixco will eventually be like puerto rico within the next 20 years... not a state but apart of us.
The real trick on keep borders safe is down in mexico.. the mexican borders to the south are highly protected by military, american and mexican. They shoot to kill there... its not a happy place to be.
The National guard will only really be down for 3 weeks so i have heard.. but that has to be wrong... i think it will be a 3 week duty shift not 3 weeks for the whole project.
