Final Election 2016 Results: What's The Republican Lead In The Senate? GOP Picks Up Victory In Senate

Republicans capped off a successful 2016 campaign Saturday by securing the final vacant seat in the U.S. Senate with Louisiana state treasurer John Neely Kennedy defeating Democrat Foster Campbell in a landslide. Kennedy, who received the endorsement of President-elect Donald Trump and Vice President-elect Mike Pence, received roughly 61 percent of the vote compared to Campbell's 39 percent.

Louisiana was the last state to officially elect its senator because of a primary system that allowed for a runoff election. Kennedy's win comes after losing to Democrat Mary Landrieu in 2008, and after losing in 2004 while running as a Democrat against Sen. David Vitter, a Republican whose seat he will fill in January.

"Ten months, 64 parishes, 23 opponents, one sitting governor, thousands of miles traveled, I don’t know, 20 debates, here we are, together, and we won. Thank you, Louisiana," Kennedy said during his victory speech in Baton Rouge, Louisiana. "This campaign was about change versus status quo."

The victory means the Republicans will control the White House, as well as the 115th Congress with a 52-48 advantage in the Senate and a 241-194 advantage in the House. The Republican National Committee was quick to celebrate its surprising Election Day success, as well as point toward future goals for the next administration while echoing the president-elect's rallying campaign slogan.

"With 52 seats in the U.S. Senate, we are excited for Republicans to confirm a conservative Supreme Court justice and begin working with President-elect Trump to pass an agenda of change for the American people," Sharon Day, the Republican National Committee’s co-chair, said in a statement. "Whether it's winning the White House, Congress, or state-level races, Republicans have much to celebrate this year, and the RNC is ready to get to work to 'Make America Great Again.'"

Meanwhile, reports from the U.S. intelligence community of Russian cyber attacks possibly influencing the presidential election in favor of Trump have caused continued debate over the results just before the Electoral College casts its official vote on Dec. 19.

The Clinton campaign announced its support for a group of 10 electors demanding a classified intelligence briefing on the Russian government’s involvement in the presidential election, while a number of "moral electors" have vowed not to vote for Trump despite their state voting for the New York businessman.
