Focusing on demographics change used to be a winning position for democrats, it has now completely turned against them. Latinos used vote for them upwards of 3 to 1, now is close to even. And when the electoral votes get readjusted in 2030 according to the new census Democrats are going to feel a demographic pain. If this new census had already been in place Trump would have easily won without any of the rust belt states, except Ohio which is not even a swing state anymore.
