Oh please. Congress changed hands because it did not use its Republican majority to effectively pursue a Republican agenda. What are the accomplishments over the last six years? The war on terror at least on the domestic front, a couple of tax cuts, and two conservative appointments to the SCOTUS. Despite a significant Republican majority in both houses as well as the White House, we still do not have anything that resembles a realistic energy policy, social security reform, school vouchers, fiscal responsibility, or smaller government. And while the Dems are as corrupt as ever, some of our reps aren't much better. The bottom line is that there has been a gross failure of leadership in both houses, and since the leadership is elected by the members who we nominate and elect, we have no one to blame but ourselves.
Good analysis.
We failed to promote leaders, and lost as a result.
