The Democrats on the Committee on the Judciary are among the most partisan in Congress...as are the Republicans. They are so for the very reasons we're seeing now; confirmation of judges.
The liberals are going to lose this and they know it now. That said, they are using this process to run their bullshit liberal propaganda to the sheeple.
During the Ginzburg hearings, she politely refused to answer the case-specific questions designed to discern how she would vote. The same rule ought to be applied to Roberts...but as we all know, that was then and this is now. A different party is now in power, and the ONLY real influence the liberals still have is in the judiciary. They will do anything to keep what little power they have and to try and set the stage for the next candidate. THAT one will be a war if Bush picks the person he ought to.
