Presidential candidates converge on Iowa for a week full of events

With six months until nomination contests begin, presidential candidates are once again converging on Iowa, the first-in-the-nation Republican primary state whose coveted nomination remains up for grabs.

On Friday night, GOP candidates will flock to the state's capital of Des Moines for the Lincoln Dinner, an event hosted by the Iowa Republican Party. With 13 candidates in attendance, the event marks one of the largest campaign gatherings in the state so far this year. Each candidate will have 10 minutes to address the crowd.
