Political analysts say they are more certain about polls this year because the public appears to be much more certain about their vote. "The polls are much more reminiscent of 2012, when there was an incumbent on the ballot and the electorate was much more decided," UVA political analyst Kyle Kondik said. "And since there are fewer undecided voters, Biden is more consistently hitting above 50% support. And to me, that is a higher-quality lead than Clinton's was because it suggests Biden has majority support."
