Iowa caucuses: What to watch as voters weigh in on the Republican campaign's first contest of 2024

As frigid temperatures scour the Midwest, the Republican presidential nominating process will officially start Monday with Iowa's caucuses.

The quadrennial contest has been unusually quiet this year, a mark of former President Donald Trump's commanding lead in the race. An arctic blast dropping the state into subzero temperatures and dumping snow during the final days of the runup didn't help, either.

But there's plenty to consider heading into the caucuses, and after years of speculation and maneuvering over who will face President Joe Biden this November, we'll finally have the first votes tallied.
