No way she goes down there now.
The implication that she's following Trump's lead could not be dodged.
Same with Louisiana. She may go for a feelgood Red Cross fundraiser or something, but certainly will not get her hands dirty on the ground with the victims.
She will go. One had to go first and one second. If she had gone first would Trump be following her lead? I do not think there is a chance she will not accept the invitation. I would be surprised. No reason for her not to.
