March 10 significance

While it’s no "Super Tuesday," March 10 comes at a critical point in the primary season, especially on the Democratic side -- where the race has effectively become a two-person contest between former Vice President Joe Biden and Vermont Sen. Bernie Sanders.

Michigan stands to be the prize of the night, as the state with the most delegates up for grabs: 125 for Democrats and 73 for Republicans.

The Great Lake State has captured the attention of Sanders and Biden, who have both spent significant time there leading up to the primary.
