shows richard blumenthal is now 13 points ahead of linda mcmahon, in the battle to replace chris dodd. a lot more races and poll numbers to bring you. that's coming up this hour, but first let's focus in on the very, very close reid verse angle race in nevada. every seat counts in the fight for the u.s. senate, but in this one it's the chamber's number one democrat who could go down in flames. dana bash is here working the story for us. take us behind these numbers. >> first of all you gave the likely numbers. i want to show you why this is trouble for harry reid, the same way it is for many other democrats. it's about the enthusiasm gap. registered voters, he's actually doing well, 43% to angle's 32%, but it's the people who say they will vote, likely voters. that's where harry rehas only 44% and angle has 42%.
