Obama leads from below after historic downgrade threatens to make him a one-termer

Here's a round-up of some of today's post-downgrade commentary, from the home page:

• Ed Morrissey: Obama retreated into the bunker after downgrade, apparently leading from below
• Conn Carroll: Blame the downgrade on ObamaCare
• NRO Editors: "Let us revisit the facts. The original debt-ceiling deal put forward by the Democrats totaled $0.00 in debt reduction"
• Byron York: The Left starting to sound like the Right in their criticism of Obama
• Pete Wehner: The history books may write of last Friday night as the point of no return from which Obama never recovered
• Barack Obama in 2009: If I don't have this economy right in 3 years, I just might be a one-termer
