To prove you’re more democrat than the democrats.
The majority of presidential candidates on both sides are bought and paid for shills for the illegal alien labor/invasion lobby.
The one politician who declares that they will play smackdown with mexico, builds and mans an effective border fortification between US and mexico, and strictly enforce existing immigration laws gets my vote
If a candidate can’t / won’t agree to that, then tell them to pack up their shit, move to mexico, and run for el presidente there.
