Rasmussen Reports’ numbers on Kagan are even worse than Gallup’s, perhaps because (as I understand the explanations of each) Rasmussen polls likely voters whereas Gallup polls American adults generally. According to Rasmussen’s most recent survey, “voters are almost evenly divided over whether Kagan should be confirmed by the full Senate: 39% say yes; 40% say no, and 20% are undecided.”
