Primary Day In Three States Today

Three states have their primaries today: South Carolina, North Carolina, and Utah. There are three major races to watch:

In South Carolina, will GOP voters choose Representative Nikki Haley as their first female candidate for Governor? She failed to get her 50% of the vote in the primary, so she's in a runoff today.

In North Carolina, Democrats will choose their challenger to an incumbent with shaky poll numbers, Senator Richard Burr (R-NC).

In Utah, a Tea Party candidate is challenging the establishment candidate to fill Bob Bennett's seat. Mike Lee, supported by the Tea Party movement, hopes to defeat Tim Bridgewater, who is endorsed by Bennett.

We'll see the results tomorrow.
