George Bush is going to nominate conservative judges because George Bush is a conservative. If you have said that no conservative minorities (or fewer conservative minorities) will be allowed on the courts, then you are effectively saying that you will not allow minorities to make the high court for as long as George Bush is president.
Anti-discrimination suits supported by those same Democrats have made it difficult for companies even facially neutral employment tests that have disparate impact on minorities. Should Democratic senators hold themselves to a lower standard than they hold private enterprise?
Hmm. Could this be a campaign commercial, do you think? It's certainly engendering skepticism in the comments section, but I'm not sure that matters for campaign-commercial material. You'd almost think that Bush was making high-profile nominations with that in mind. . . .
