A lot of the remaining ballots are provisional, so up to 1/3 could end up being thrown out. Still it looks like there will be more total votes than 2012, but not much more and likely not more than 2008.
According to
electproject.org, in 2008 there were 132,609,063 ballots counted and in 2016 there are an estimated 131,741,500 ballots counted. I also noticed that this had updated since this morning from around 129 million. Does this estimate include those seven million ballots that are not yet included? Because if it does not, they will easily push the total number of ballots cast past the 2008 number.
