No surprise, the quoted write-up from the website in question was fundamentally dishonest :
"Just a few constituents following their representative into a large bathroom to air their grievances. What should they have done instead? Call her office and direct their ire through a receptionist like surely countless Americans do each day? Write her a letter she won’t read? Vote her into office again and hope that, this time, she’ll deign them important enough to listen to?"
Go back and listen to the actual audio of the in-the-women's-room video. The young woman talking is not a constituent, not a voter, not even an American Citizen. She could not attend her grandfather's funeral because "there is no pathway to citizenship." She is a DACA.
Sinema was not followed by, nor was she hiding from, her constituents. These activists are illegal aliens trying to complete their jump to the front of the line.
