Republicans are taking advantage of their majority rule to ensure that they’ll always be in power :

Over the vehement protests of Democrats, Republicans are trying to use newly won clout in the Colorado and Texas legislatures to redraw congressional districts that are less than two years old, part of a highly unusual tactic to strengthen their control over the House of Representatives.

In Denver, Republican lawmakers pushed through legislation Wednesday that is designed to give first-term GOP Rep. Bob Beauprez political breathing room in a district he won by only 121 votes last fall. White House political adviser Karl Rove lobbied for the plan, and Republican Gov. Bill Owens is expected to sign it.
. . .
Democrats say the Congressional Research Service has found no mid-decade redistricting has occurred for at least 50 years, and they accuse Republicans of a raw power grab. “Are we going to turn this into a country where every election, whoever is in power, whoever takes the majority, then decides to redraw the lines? I think it’s really a disservice to the American people,” said House Minority Leader Nancy Pelosi, D-Calif.

What’s worse, gerrymandering is usually legal. For a more comprehensive explanation of gerrymandering, check out this site :

Gerrymandering is the legal equivalent of stealing an election by stuffing the ballot box with a sufficiently large number of fraudulent ballots voted for the incumbent, or by removing a sufficiently large number of legitimate ballots voted for the challengers before they are counted.

Hmmm…that last one sounds oddly familiar…
