Hillary Clinton's lead over potential 2016 Democratic rivals has shrunk considerably, a new poll finds.

According to the poll, from ABC News and the Washington Post, 61% of likely Democratic voters say they would vote for Clinton. This is down from last month's lead of 63%, and January's 73%. This latest poll was conducted earlier this month and released on Sunday.

Vice President Joe Biden is a distant second with 14% of the potential vote.

Mass. Senator Elizabeth Warren comes in third at 13%. The same survey last month found that she was only commanding 11% of the vote. In January, that number was only 9%. Warren has repeatedly denied that she is seeking a bid for president.
