Heidi was in the audience, too! That De Moines Register link I posted has all the photos, speeches, etc from the event.
That feed kept rebooting for me no matter what adjustments i made...and C-Span cuts off after a certain time limeit...though you can bring it back up right away.
All in all those who really counted “served” their purpose I think...but you can tell who are Really the candidates....and others filling in...
BTW Christy did mention he’s a candidate...though I think it was a slip and not intentional
