"If Robin Carnahan had faced off against Roy Blunt in any election year between 1996 and 2008 she would likely have won given her superior popularity," PPP's Dean Debnam says in a polling memo. "But 2010 has the potential to be an extremely good year for Republicans, and that's made this race highly competitive."
