Clinton, once the prohibitive front-runner, is now the top choice of 33 percent of registered Democrats and those who lean Democrat, the poll shows. Biden places second with 25 percent and Vermont Senator Bernie Sanders is at 24 percent. The other three Democratic candidates combined are the top choice for less than 4 percent of that base…

The latest Bloomberg survey shows the vice president at par with Sanders in terms of Democratic support nationally. Adding to the good news for the vice president: His favorability ratings are on the rise. Since the last Bloomberg poll in April, Clinton’s favorability ratings have dropped 10 points, from 48 percent to 38 percent. Biden’s 49 percent favorable score represents a 3-point uptick. He was the only one of a dozen national political figures and entities whose approval rating improved over the summer.
