It's obvious that both campaigns think Clinton won the debate, so that ought to make it clear who won. Not that some people won't continue to be cloudy.
One difference between liberals and (at least some) conservatives. Liberals flat out admit it when they lose. I didn't see anybody claim that Obama beat Romney in the first debate in 2012. I didn't see anyone claiming that it was somehow rigged for Romney either.
And let's be real here. Clinton won much bigger against Trump than Romney won against Obama. The only reason one might not think so is because how incredible low the bar was set for Trump.
The guy on the (conservative) Weekly Standard podcast thought that the beatdown of Trump was the biggest beatdown in presidential debate history and looking at it objectively - without the low expectations for Trump clouding perception - I think he was spot on.
