2010 U.S. Senate Election Results - The Winners and Losers

Results: Democrats 53 seats, Republicans 47 seats


Hawaii 2010 U.S. Senate Race

Incumbent: Democrat Daniel Inouye, eight terms
Running for reelection

Opponents: As projected, incumbent 86-year-old Democratic Sen. Daniel Inouye won by a wide margin over Cam Cavasso, a wealthy conservative businessman and former 3-term member of the state legislature.

In the 112th U.S. Senate, Sen. Inouye will have the most seniority, and will chair the influential Senate Appropriations Committee.

Sen. Inouye won 76% of the statewide vote in his 2004 reelection bid. The senator has been a member of Congress since Hawaii became a state in 1959, and a member of the Senate since 1963.

Idaho 2010 U.S. Senate Race

Incumbent: Republican Mike Crapo, two terms
Running for reelection

RESULTS: As expected in red-state Idaho, incumbent Republican Sen. Mike Crapo easily defeated Democrat Tom Sullivan, a small business owner.

Republican Sen. Crapo generated " $4.3 million in campaign donations, while Sullivan struggled to gain much traction after raising only about $70,000," per local Idaho press.

Sen. Crapo received 99% of the statewide vote in his 2004 reelection, after running unopposed.

Illinois 2010 U.S. Senate Race

Incumbent: Democrat Roland Burris, appointed to replace Barack Obama
Not running for election

RESULTS: Five-term Republican Rep. Mark Kirk narrowly defeated Democrat Alexi Giannoulias, State Treasurer, in a stunning conservative victory in blue-state Illinois. Both President and Michelle Obama personally campaigned for Democrat Giannoulias.

In June 2010, Republican Kirk was caught exaggerating his military service record.

However, Democrat Giannoulias hails from a prominent Chicago family whose business, Broadway Bank, was seized by federal regulators in April 2010 amidst allegations of questionable associations and activities.

Indiana 2010 U.S. Senate Race

Incumbent: Democrat Evan Bayh, two terms
On February 15, 2010, Bayh announced that he won't seek reelection, citing the bitter partisanship of Congress.

RESULTS: As expected, Republican Dan Coats, who served as U.S. senator from 1989 to 1999, easily won over his Democratic opponent, two-term Rep. Brad Ellsworth. Ellsworth, a former sheriff, is a member of the centrist House's Blue Dog Democrats.

Republican Coats retired from the U.S. Senate to be a D.C. lobbyist. He served as U.S. Ambassador to Germany for four years under President Bush.

Iowa 2010 U.S. Senate Race

Incumbent: Republican Chuck Grassley, five terms
Running for reelection

RESULTS: As projected for red-state Iowa, incumbent Republican Sen. Chuck Grassley won reelection for a sixth six-year term in the U.S. Senate over Democrat Roxanne Conlin, an attorney who previously served under President Jimmy Carter as United States Attorney for the Southern District of Iowa.

Per the Des Moines Register, "Conlin deserves credit for her campaign. She kept it mostly focused on the issues when most candidates in her position were slamming opponents on their personal lives. She offered ideas and proposals of her own, not just a repudiation of Grassley’s record."

Kansas 2010 U.S. Senate Races

Incumbent: Republican Sam Brownback, two terms
Not running for reelection

RESULTS: Seven-term Republican Rep. Jerry Moran won over Democrat Lisa Johnston, an educator who holds a Ph.D. in Educational Leadership.

Republican Moran will fill the Senate seat held for the last twelve years by retiring Republican Sen. Brownback, who won his 2004 Senate race with almost 70% of the vote in red-state Kansas. Rep. Moran won the Republican senatorial nomination won over the Sarah Palin-endorsed candidate.

Predicted CQPolitics, "Kansas Democrats have not won a Senate seat since 1932 and the November contest will be a cakewalk for Moran."


Kentucky 2010 U.S. Senate Race

Incumbent: Republican Jim Bunning, two terms
Not running for reelection

RESULTS: Republican Rand Paul won over Democrat Jack Conway, Kentucky state Attorney General.

Republican Paul was strongly back by the ultra-conservative Tea Party movement, and has espoused controversial views about civil rights and on other issues. Rand Paul is the son of 2008 president candidate Ron Paul, a seven-term Congressman from Texas.

Louisiana 2010 U.S. Senate Race

Incumbent: Republican David Vitter, one term
Running for reelection

RESULTS: Incumbent Republican Sen. David Vitter prevailed in a bitter contest over two-term Congressman Charlie Melancon, a member of the Blue Dog Democrats. Vitter won despite his entanglement in a messy prostitution scandal.

Per local press, "Melancon called Vitter 'hostile to women'" and "cited a Vitter vote against an equal-pay law." Vitter had dubbed Melancon "too liberal," citing "Obama policies of endless bailouts, failed stimulus, massive debt" and health care reform.

Maryland 2010 U.S. Senate Race

Incumbent: Democrat Barbara Mikulski, four terms
Running for reelection

RESULTS:Democratic incumbent Sen. Mikulski easily won reelection for a fifth term in the U.S. Senate over Republican Eric Wargotz, a county commissioner since 2006. Sen. Mikulski won 65% of the vote in her 2004 reelection.

Wargotz, physician and professor, won the Republican nomination over 10 other Republicans by spending from his substantial fortune.

Sen. Mikulski won handily while other Democrats nationwide foundered partly because she openly expressed reservations about President Obama's agenda. Reports AP, "She says he's done a 'credible' job but calls herself an independent who won't be a rubber stamp for the administration."

Massachusetts 2010 U.S. Senate Race - Partial Term


Republican Scott Brown upset favored Democrat Martha Coakley to fill the Senate seat held by Ted Kennedy, despite registered Democrats outnumbering Republicans 3 to 1 in the Bay State. Voter anger was fueled by Obama health care legislation, the economy, and Wall Street bonuses.

Incumbent: Democrat Paul Kirk, who assumed office on September 24, 2009 after the passing of Sen. Ted Kennedy.
Not running for reelection.

Candidates - On December 8, 2009, state Attorney General Martha Coakley won the Democratic primary to fill the U.S. Senate seat left vacant by Sen. Ted Kennedy's passing. In the special election held on January 19, 2010, Democrat Coakley faced Republican Scott Brown, a three-term state legislator.
