WASHINGTON (AP) — The dog days of summer are over for the Democratic presidential candidates.
In just five months, voters will begin to get their say in the 2016 race.
And on this Labor Day weekend, the White House hopefuls are descending on Iowa for town hall-style meetings, union picnics and chicken cookouts.
The burst of activity marks the start of a more intense phase in the primary.
How the candidates position themselves in the coming weeks could have a big impact on their standing in February when primary voters make their choice in key early-voting states.
