When will the presidential field start to shrink?

The Iowa caucuses are just weeks away, marking the first votes cast on the road to the White House in 2024.

Throughout this year, the race for the White House has been pretty consistent as former President Donald Trump has led by a wide margin in the polls for the GOP nomination.

Meanwhile, President Joe Biden has faced limited opposition from Democrats. 

Over the course of the next several weeks, expect a lot of changes among Republicans.

Traditionally the Iowa caucuses and the New Hampshire primary are periods of time in which some campaigns take off while others sail into the sunset.

Many Americans may be taking a good chunk of the rest of the year off, but other than a quick Christmas break, the Republican presidential campaigns are not.
