Could the GOP stoop any lower?

How far has the GOP and its supporters fallen (yes, I'm aware that not all members of the GOP share these sentiments) when they are publicly calling Sen. Obama a "traitor" and yell chants to have him put to death? Also, what does it say about Sen. McCain's character for not condemning such disgusting actions?

John McCain has shown a stunning failure of leadership. His campaign, in a time of economic crisis and foreign policy drift, has degenerated into a negative and nasty campaign of smears. The reports are piling up of ugliness at the campaign rallies of John McCain and Sarah Palin. Audience members hurl insults and racial epithets, call out "Kill Him!" and "Off With His Head," and yell “treason” when Senator Obama’s name is mentioned.
