Clinton supporters were trumpeting a poll that showed her with a double digit lead over Donald Trump. However, I believe that poll was an outlier. The polls to watch are actually the daily tracking polls, and they reveal a much tighter race.
When you dig deeper into the numbers, things get really interesting.
A significant portion of Clinton's support comes from groups that historically don't turn out to vote on election day.
As well, Trump's support among one very important group is quite strong and could turn the election in his favour...
