The account has his name on it. It is his account.
Sure. And it’s his face on the billboard, and so on. When your name and face are regularly handed off to others to create a message to associate with it, sometimes the best you can do is pull the offending material after-the-fact and presumably identify/deal with the person who created it. If you consider Twitter passwords to be sacrosanct things only to be given to people with the highest vetted clearance, you would be (perhaps properly) horrified by how it works every day in much of the world, where the intern gets handed it on day 1.
If it is the case that any new intern gets handed the password on day 1, I would suggest changing the name of the twitter account. Maybe change it to “Ted Cruz campaign” or “The Office of Ted Cruz” or “Ted Cruz INC” or “The Staff of Ted Cruz”. Something that indicate it is a twitter account belonging to his group(what it is called), and not his own private twitter account.
But, politically, he can’t. Cruz represents about 28 million constituents (which is appalling but true). And yet people who go through the trouble of writing to (or e-mailing, or tweeting, etc) their Senator want to feel like they got a one-on-one exchange with a US Senator, where their opinion was, at least temporarily, given the undivided attention of someone who could actually help. Which is ridiculous even for a decent Senator, let alone the likes of Cruz.
If you get a response back from “the office of Ted Cruz”, or “one of about twenty interns who just started working this month for Ted Cruz” – yes, it’s honest and accurate, but it’s politically counterproductive. It gives the voter the (probably accurate) impression that the Senator most likely will never set eyes on what most people write to them, which doesn’t exactly make you have good feelings about them come re-election time. So they keep up the facade of “oh yes, you’re really communicating with me personally” because it makes them seem like the sort of Senator people want to have.
It’s not just social media. Write a letter, and you’ll get a letter back signed by the Senator (well, with a printed image of the Senator’s signature). The return address will say the office of so-and-so, but the letter itself will look personal. I’m dating myself here, but I wrote a letter to the newly-elected Bernie Sanders when he was in the House, and when he actually wrote back it was like Christmas. OMG! Mr Smith goes to Washington WORKS! Woohoo citizen democracy! But seriously, upon reflection, it was just a form letter.
Showbiz and politics. Not so different after all.
