CNN senior political analyst David Gergen gushed over Al Gore’s speech at Invesco Field on Thursday evening during the network’s coverage of the Democratic convention as he urged viewers to go back and read the text:

I think the Gore speech, he -- while it was way too rushed in delivery, had an awful lot to offer, and was one of the first times anybody in this campaign has spoken seriously to the nation about the potential catastrophe coming from global warming.... I think it's really was worth for a lot of people going back and actually reading the text of Al Gore's speech.

He then mentioned Abraham Lincoln’s "brief time in politics before he became President" in an indirect reference to Barack Obama’s short political career.
