WASHINGTON (CNN) As candidates for the Democratic nomination for president in 2020 begin to declare their intentions, a handful of potential candidates hold on to most of the early support, according to a new CNN poll conducted by SSRS, and Texas Congressman Beto O'Rourke is a new addition to the top tier. Former Vice President Joe Biden continues to top the list when the potential Democratic electorate is asked who they'd be most likely to support for the nomination, with 30% saying they would back him. Vermont Sen. Bernie Sanders lands in second with 14%. O'Rourke lands in third with 9%, up 5 points since October. California Sen. Kamala Harris and Massachusetts Senator Elizabeth Warren have each dropped 5 points since October and are now below 5% support.
