I remember watching in 2012 (I think), and the instant the California polls closed, they called the election for Obama. I think that was 11pm my time and I was all ready for a long night in front of the TV waiting.
Sounds about right @HoldMyLobster
I was watching Jon Stewart in 2008 and I remember him announcing Obama at the 'beginning' of the Daily Show, which started for us at 8pm.
I don't know if the cable stations (CNN et al) hold back like the local networks do. I figure I'll start tuning in about 5pm 'my time'. That'd be around 8pm yours and about when the 'westward sweep' of closing polls should start.
DH has relegated me to the bedroom to watch. I'm good with that. Much less disturbance that way.
