U.S. SENATE RESULTS
What happened: In Missouri, Robin Carnahan easily defeated Richard Tolbert and Francis Vangeli with 83 percent of the total votes.
In Boone County, Carnahan took 89 percent of the vote to Tolbert's 6 percent and Vangeli's 4.5 percent.
Issues: During the campaign, Carnahan said getting the economy back on track was her top priority, arguing that Washington was broken and needed to be brought back under control. While Carnahan is a Democrat, she said her party loyalty wouldn't necessarily mean she would side with President Barack Obama.
During the campaign, Tolbert said his decision to run resulted from Secretary of State Robin Carnahan's lack of support for Obama. Tolbert supported government bail outs and an immigration reform that uses labor as a punishment.
Vangeli said he opposed abortion, food stamps and welfare and was in favor of lowering taxes.
What happened: Roy Blunt won the Republican primary with nearly 71 percent of the vote against Davis Conway, Tony Laszacs, Hector Maldonado, Kristi Nichols, Bob Praprotnik, Chuck Purgason, Deborah Solomon and Mike Vontz.
In Boone County, Blunt earned 70 percent of the vote over the other contenders.
Issues: Blunt's promised to fight for Missourians on issues such as the economy, jobs, energy and spending cuts.
"If Missourians believe Nancy Pelosi, Harry Reid and Barack Obama need more help enacting liberal policies in Washington, they want Robin Carnahan. But if they want a U.S. senator who will fight for Missouri jobs and families, they ought to support our campaign," he said.
Conway said his focus was on the economy and education. Laszacs said he wanted to reform the education system, expand fuel efficiency standards and build a functional health care system. Maldonado campaigned on tax incentives and tax breaks for small businesses. Nichols said she would require a balanced budget and work to cut deficit spending.
Praprotnik said he wanted to cap spending and focus on cutting foreign aid donations and end U.S. membership with the United Nations. Purgason said immigration, job creation and the economy were his primary issues.
Solomon campaigned on finding balance between education and moral stability, a balanced budget, promoting religious freedom and fair wages. Vontz said his primary goal was to turn the economy around and bring the government under control.
What happened: Jonathan Dine defeated Cisse Spragins, winning 59 percent of the vote.
Dine took 53 percent to Spragins' 46 percent in Boone County.
Issues: Spragins said she wanted to "reduce the size, scope and power of the federal government," repeal the Patriot Act and fight against the "government's drug war."
Dine focused on individual liberty and freedom and supported the legalization of marijuana. He said he wanted the government's primary role to be protection of its citizens.
What happened: Jerry Beck defeated Joe Martellaro and Mike Simmons. Beck won with 45 percent over Martellaro, 27 percent and Simmons, 29 percent.

Issues: Martellaro said the only major issue for him was reforming federal government to ensure personal liberties and to return to the principles of the Constitution.
