Denver in 2008: Obama clinches Dem nomination. Denver in 2011: Shame on Obama!

Occupy Denver Rally starts from the Greek theater in the Civic Center Park on Saturday. Three years ago, Barack Obama accepted the Democratic Party's nomination for president at the convention in Denver. I was there, cheering him on. Now Occupiers are holding up images of Obama that say "Shame." I was there 10/8/11. What is going on? Will Denver be the place that both launched Obama's career and also brings him down?
