The Dems don't care about border security, period. They support the constant influx of new socialist voters, view the dead Americans as collateral damage in the march toward their greater good and jobs going to illegals at the expense of the American middle class as the cherry on the parfait.
They hate Donald Trump for being the only president in our lifetimes to go against the grain and make an issue out of it. They hate even more the American people who agree with him.
