They do.
They imported active Ebola patients, they did nothing about plague in San Fransisco's China Town, they closed immigrant screening at Ellis Island, They've thrown open our borders, they import jihadis as fast as they can, they create sanctuary cities, they release violent felons, they refuse to cooperate with ICE, and they allow their streets to be overrun with rats and to be covered in poop and needles.
They know exactly what they are doing.
Keep voting democrat, cuz they care so much about you.
