Silly because you are worried just because the President refused to be trapped by a dumb question by a liberal member of the MSM.
Did you happen to actually read the questions I have? His laugh-off of that question was hardly a key concern. With comparisons to Souter already abounding, the joking non-answer to whether Souter was a mistake is just another brick in that wall of concerns, and comes poorly-timed. Now, if it were, say Edith Jones, then it could be laughed off.
Would you still laugh it off if they had asked President Bush whether Stevens, Breyer and Ginsburg were mistakes as his nominee was being compared to them, and he gave essentially that laughing non-answer?
