Important to keep in mind that there really are very, very few “undecided” voters. Studies have show that something like 90% of voters in Presidential elections who call themselves undecided end up voting for the same party they did in the last election.
Or not voting at all. Black turnout will not reach the levels of 2008 and 2012.
We call them “clueless Obama voters”. Soon to be “brainless Hillary voters”.
