Once the early polls open you will see media reports and "experts" trying to read the tea leaves of the polls predicting a winner but there are many pitfalls, said voting turnout specialist Michael McDonald, associate professor of political science at the University of Florida and a nonresident senior fellow at the Brookings Institution.
"There are a lot of nuances in early balloting and you will see a lot of ebb and flows," said McDonald, who runs the United States Election Project. "The early part of balloting is by mail-in votes which Republican early voters prefer so you will see Trump supporters saying the media polls are wrong and Trump is winning. But then you'll have the physical polls open (which) the Democrats prefer and Clinton will then catch up. Bottom line — you will get the clearest picture a week before the election on who is ahead in the general election."
The lack of clarity has a least one CEO in no rush to vote early. Mike Jackson, chairman, and CEO of AutoNation, said he will not be casting his vote early because the campaign policies and rhetoric have left him somewhere between depressed and despondent.
"The one word that sums up this election is never. Voters say they will never vote for Clinton, or they will never vote for Trump. There is little enthusiasm as to who they will vote for." Jackson said. "Based on his temperament, I will never vote for Trump. Down ticket, I will split my vote which will be mainly Republican. As to who I vote for president, well if this was the Clintons of the '90s then I would say I would vote Hillary. But based on her rhetoric, just how far left has she gone? So while I've decided who I will NEVER vote for, ... it's still to be determined who I will vote for."
Barry Jackson, managing director of The Lindsey Group who advises clients on the impact of existing and potential policies on business, told CNBC the campaigns for Clinton and Trump are the least substantive campaigns he has ever seen in addressing fiscal policy, and it's unknown if it will have an impact on early voting.
"There is no simple answer on that — enthusiasm versus ground game versus unknown actions of the anti-Hillary crowd on the Dem side and the 'never Trump' crowd on GOP side."
