At present it looks unlikely that fighting John Roberts candidacy will win them any political mileage. It might be prudent for the Democrats to pass on this battle and instead go after the Karl Rove controversy.
The Democrats were all geared up for tet another battle as President Bush was ready to announce his Supreme Court nominee. With the selection of John Roberts, President Bush has foxed his opponents once again. A virtual unknown, the Democrats are going to have a hard time digging up dirt on this candidate. The conservative groups appear to be pretty happy with this choice too. In short, President Bush has kept his base happy and made life hard for his oppenents.
