Super Tuesday Battles Included Key Senate Contests Katherine Gypson CAPITOL HILL - Super Tuesday primaries in 14 states across the country shifted momentum in the presidential race from progressive Senator Bernie Sanders to former Vice President Joe Biden. But the race to see which Democrat will challenge President Donald Trump in the November general election was far from the only contest with far-reaching political consequences. Primary voting in a handful of key states also revealed more about Republicans' battle to maintain control of the U.S. Senate. Democrats have held the majority in the U.S. House of Representatives for the last two years and hope to wrest away control of the Senate. Democratic control of both chambers would have a major impact on the next president's term in office, regardless of party. If he's reelected, Trump would have a hard time passing any major legislation through a Democratic-controlled Congress. And a President Biden or Sanders would be unable to get their ambitious agendas off the ground if the Republican majority in the Senate holds. Currently, Republicans hold a 53-47 majority in the chamber. Analysts say Biden's success Tuesday points to a way forward for Democrats to take control of the U.S. Senate. "There is a desire to continue to kind of go forward with what was the 2018 strategy for Democrats that was very successful for them," said Dr. Lara Brown, director of the Graduate School of political management at George Washington University. "That strategy is really about finding candidates who fit their constituency, mostly those candidates in large statewide races that are going to be more moderate rather than progressive." Alabama .
