Democrats will maintain control of the U.S. Senate as Nevada Sen. Catherine Cortez Masto is projected to defeat her Republican challenger, Adam Laxalt, in a tightly contested midterm race in The Silver State. With Democratic Vice President Kamala Harris being the tiebreaking vote, Democrats will again have a narrow majority with at least 50 seats in the upper chamber for the second half of President Joe Biden’s first term in office with the potential to expand the majority with Georgia's runoff election next month.
