She's an idiot.
If Trump can get good border security and other meaningful immigration reform, and the price is letting DACA recipients stay, then that's a deal you take 10 times out of 10. Especially in an election year.
The "they all must go, including the DACA recipients" argument is a loser with too many voters. The consequence of adhering to that position would be increasing the likelihood of electing a Democrat who will essentially support complete amnesty for everyone here illegally.
