Republicans have seized control of the Senate and strengthened their hold on the House in a wave of Election Day victories.

Senate Republican leader Mitch McConnell defeated his Democratic challenger in Kentucky, putting him in position to become the new Senate majority leader.

Republicans picked up Senate seats in seven states.

And Republicans are on track in the House to meet or exceed the 246 seats they held during President Harry Truman’s administration more than 60 years ago.

Republicans also swept governor’s races across the country, scoring upsets in Democratic bastions like Maryland, Massachusetts and Illinois.

The Democrats’ only significant victory came in Pennsylvania, where businessman Tom Wolf ousted GOP Gov. Tom Corbett.

Three contests remain too close to call: Alaska, Colorado and Connecticut.

House Speaker John Boehner is telling Republicans that despite victories in the House and Senate, it’s “not a time for celebration.”

Boehner says instead, it’s time for government to start “implementing solutions to the challenges facing our country.” He says those challenges begin with what he calls a “still-struggling economy.”

Most voters would agree with that. Exit polls showed voters don’t have much trust in government, feel the nation is off on the wrong track and believe life will be worse for the next generation.

And above all, voters surveyed while leaving the polls say they’re worried about the economy. People who say their own financial situation grew worse in the past two years voted for Republican congressional candidates by a 2-1 margin.
