Shouldn’t be that hard to find her. Reporter worth his/her salt would check the hotel where Hillary spent the night in Iowa and see if the entire party checked out. She may be holed up there. Next step would be to check with the airlines/TSA and see if Huma turns up on passenger lists out of Des Moines today. They could also use on-line tools to track the flights of aircraft chartered by the Clinton campaign.
If it was a Republican operative, TV news crews would be camped out at her house or apartment. I’m sure many on the Clinton campaign plane know where Huma lives, but they’re going to respect her “privacy.” Of course, Huma isn’t there. Tucked away with the lawyers while they decide her course of action.
Fleeing to the Middle East is very much an option, but only after election day. Until then, Huma will be the invisible woman.
