Dunno if she's in better health. The falls may be happening out of camera range. Look at her recent photos like from Georgetown carefully. The Clintons may still have Lenin's make-up artist on retainer, but they can't hide the puffiness under her eyes. That's new since November.
My own guess is that she's been on a bender since 9:00 PM on election night, and that she's more likely going to be a candidate for a liver transplant than a candidate for President by 2020. But that's just my guess.
Jerry Brown will be 82 in 2020, and he's the Democrats' "youth candidate".
Tough one to answer....
