68-year-old Rep. Diana DeGette got caught on video snapping at a constituent asking why she voted to send bombs to Israel: "If the only issue that you care about is this issue, then you should not vote for me." She lost her primary to Melat Kiros, a 29-year-old Democratic Socialist. The moment DeGette tried to shame voters for caring about Gaza is now her political epitaph. This is what happens when you treat your base like children instead of constituents with legitimate grievances.
