Or is it simply history repeating itself ... \n the party controlling the White House nearly always loses House seats in midterm elections" — especially in the sixth year. \n In Franklin D. Roosevelt's sixth year in 1938, Democrats lost 71 seats in the House and six in the Senate. \n In Dwight Eisenhower's sixth year in 1958, Republicans lost 47 House seats, 13 in the Senate. \n In John F. Kennedy/Lyndon Johnson's sixth year, Democrats lost 47 seats in the House and three in the Senate. \n In Richard Nixon/Gerald Ford's sixth year in office in 1974, Republicans lost 43 House seats and three Senate seats. \n Ronald Reagan, lost five House seats and eight Senate seats in his sixth year in office.\n  Clinton- Republicans picked up a total of 49 House seats and nine Senate seats in two midterm elections. When Clinton won the presidency in 1992, his party actually lost 10 seats in the House — only the second time in the 20th century that a party won the White House but lost seats in the House

There are 49 Democrats and 49 Republicans, with 2 independents.  But both independents will caucus with the Dems (voting to determine senate leadership), so the control of the Senate will go to the Dems.  For voting purposes, it is pretty much evenly divided, depending on how the independents vote (Lieberman will probably tend Republican on foreign policy matters, Democrat on domestic policy issues).

We have a two party system.  It's the democrats and the republicans.  Right now, the Republicans are "in power" holding the bulk of the power in Congress and the Senate along with the Presidency.  The Democrats would be the opposition, but I've never heard it put quite the way you did.

Democrats would need to win control of Congress in the upcoming elections. If that doesn't happen you can forget about it. The Republicans would never let it happen.

How quickly we forget. Yes, this has happened many times in the last century.\n\nFrom 1993-1995, in President Clinton's first term, Demcrats held a commanding majority in the House and a very slim majority in the Senate. During that Congress, the Republican majority (according to the Wall Street Journal) set a record for the most fillibusters staged in a two-year period.\n\nFrom 1977-1981, during President Carter's entire term, the Democrats held commanding majorities in both houses. Because of in-fighting, the Congress was reduced to ineffectiveness.\n\nFrom 1961-1969, during the shortened term of President Kennedy followed by the full term of President Johnson, Democrats held majorities in both Houses.\n\nFrom 1933-1949, during the terms of President Roosevelt and President Truman, Democrats held majorities in both Houses. In 1949, Republicans took control of the House of Representatives but not the Senate. From 1951-1953, during President Truman's second term, Democrats held majorities in both Houses.\n\nThis is why, when the Gingrich Revolution took control of the Senate and the House in 1995, Conservatives were able to say they were coming back to power in the House for the first time in over forty years.

No one party "controls" the U.S. Senate. There are more Republicans sitting in the U.S. Senate right now than Democrats. But each of those Republicans are free agents and capable of voting against the wishes of their party leaders. Also, just because there are fewer Democrats in the Senate right now than Republicans, that doesn't mean that they have no influence over what the Senate produces.
