With Vice President Joe Biden officially out of the presidential race, the nation’s first nominating contest between front-runner Hillary Clinton and Senator Bernie Sanders is gaining steam, according to a new Bloomberg Politics/Des Moines Register Iowa Poll.

Clinton leads the field with 48 percent of likely Democratic caucus-goers when Biden’s supporters are re-allocated to their second-choice candidates; Sanders is in second place at 41 percent. Clinton led Sanders by a similar margin of 43 percent to 35 percent in the Iowa Poll conducted in August.

With Biden in the mix, he received the support of 12 percent of likely Democratic caucus-goers in the October poll, cutting Clinton’s advantage to 5 points from 7 points. Without him, his supporters split almost evenly between the leading alternatives: Clinton’s support went up 6 points, Sanders’s 4 points.
