Waddling is the most I'd go with.
I’m a thinking she’s going to be offering herself as VP to the 2 doddering fools ready to cash it in.
“Im just offering my support to your campaign”.
“I have many supporters who will vote for the ticket”
“I have great experience to help you”
Then they get a ‘health scare’ and resign to her Hugeness moving up..
LOL. I always thought Hillary lumbered but I now see you are much closer to an accurate description of her movement.
