Congress underscores Bush's weakness
The BBC's Richard Allen Greene in Washington writes his weekly diary highlighting key issues in the US mid-term elections.
In my neighbourhood in Washington, George W Bush's presidency is already over.
You can see it on the T-shirts, such as the one that simply says: "20 January 2009", the day Mr Bush will step down and hand power to whoever wins the 2008 election. And you can see it on the bumper stickers.
I have already seen a car with "Clinton/Obama 2008" plastered on its rear, articulating the hope of many liberals that Hillary Clinton will run for president, with the mixed-race first-term Senator Barack Obama as her vice-presidential choice.
Mr Obama, one of the few true media stars of the Senate, set journalists' pulses racing this week with a trip to Iowa.
