You now have six-year campaigns for the Senate - you never stop running. It's not uncommon for a member of the Senate to have a fundraising breakfast, a fundraising lunch and a fundraising dinner, and then when the Senate breaks for the week to go home, more fundraisers. And that's driven by the cost of campaigning.
Filibusters have proliferated because under current rules just one or two determined senators can stop the Senate from functioning. Today, the mere threat of a filibuster is enough to stop a vote; senators are rarely asked to pull all-nighters like Jimmy Stewart in 'Mr. Smith Goes to Washington.'
Of course, the genesis of a good portion of the gridlock in Congress does not reside in Congress itself. Ultimate reform will require each of us, as voters and Americans, to take a long look in the mirror, because in many ways, our representatives in Washington reflect the people who have sent them there.
The amount of U.S. debt held by countries such as China and Japan is at a historic high, with foreign investors holding half of America's publicly held debt. This dependence raises the specter that other nations will be able to influence our policies in ways antithetical to American interests.
