Forget the end of summer, Labor Day is the unofficial start of the final sprint to Election Day for presidential campaigns.
So, while many Americans will be thinking about starting school, not wearing white, and the option of having pumpkin flavored beverages, Hillary Clinton and Donald Trump will be fighting to win over voters during a quickly closing window.
Both campaigns are now facing a number of key dates this fall that have the potential to shape the final outcome of the campaign. Trump has trailed Clinton both nationally and in the key battleground states since the end of the party conventions in July but her lead has narrowed in recent days. Now the stakes grow higher each day as a series of milestone markers loom large beginning this week.
