DES MOINES, Iowa - President Barack Obama is asking Iowa voters to help him finish what they started in the state four years ago.
In his last political rally as a candidate, Obama says Iowa voters helped start "a movement that spread across the country."
More than 20,000 people are attending the outdoor rally on the eve of Election Day.
For the president, the Iowa rally is steeped with nostalgia. His win in the state's 2008 caucuses jumpstarted his first presidential bid. And his last rally Monday night is being held in front of the building that housed his campaign headquarters during that election.
