is more commanding. again, this is nationally. she goes up 11 points. if biden does not run senator sanders up by about four points. hillary clinton came out of this debate a bit strengthened in the national polls. not a lot but a little bit. if biden doesn't run she's still in a commanding place as we wait and wait and wait for that decision. >> and we are also looking at this poll to find out if democrats want vice president joe biden to run. what are we being told there? >> an interesting number. not an overwhelming shift but look at this for the vice president. in august 53% of democrats, democrats, said mr. vice president please jump in join the fray. after the debate just 47% say mr. vice president join the race. so a six-point drop. could that be they're just tired of waiting? could it be they like the candidates they saw on the debate stage? could be a combination of those things, most likely. but as the vice president approaches decision we're told any time definitely by the end of the month. could take note fewer democrats say come in.
