That money is meant, in good faith, to help the candidate campaign. If your campaign then goes dark for 2 weeks, you owe your donors an explanation and peddling some bull**** like "oh he's just got the flu" is unacceptable. If your candidate is incapacitated...the ethical thing to do is to give back that donor money.
When I was campaigning, I was doing vitamin IV's, we had a full on supplement regime, I wouldn't even drink water out of plastic bottles...I owed it to my donors and my supporters to be firing on all cylinders, nonstop; you can't afford to have a down day, let alone a down week...or 2 weeks, now, in Talarico's case.
Unless they're pulling some bizarre viral PR stunt, and we're just waiting for the punchline...what these advisors are doing is despicable. It's bad enough if they drove their candidate into the ground, but this "damage control" radio silence is just wild. Incredible cowardice and incompetence on display here.
