Republican supporters cheer as a giant TV screen displays the results of the Senate race in the U.S. midterm elections in Denver, Colorado, November 4, 2014.

Republicans won control of the U.S. Senate, capturing seats from Democrats in elections Tuesday shaped by deep voter discontent with President Barack Obama.

With Republicans retaining their majority in the House of Representatives, Obama will spend his final two years as president contending with a Congress fully controlled by opponents who have been determined to block his policies.

Republican won at least seven seats now held by Democrats, while Democrats failed to pick up a single Republican seat. That assures the Republicans of at least 52 votes in the 100-member chamber.

Among the Republicans re-elected Tuesday was the man who would likely become majority leader if the party captures the Senate: Mitch McConnell of Kentucky. Democrats once had high hopes of defeating him, but he pulled away in the final weeks.
