I'm just reading this myself, but I thought I'd bring your attention to it:
Lott, Reagan and Republican Racism
If the GOP wants to attract black voters, argues TIME's Jack White, it must confront the legacy not only of Trent Lott, but also of former President Reagan
By Jack White for Time magazine.

Then there was Reagan's attempt, once he reached the White House in 1981, to reverse a long-standing policy of denying tax-exempt status to private schools that practice racial discrimination and grant an exemption to Bob Jones University. Lott's conservative critics, quite rightly, made a big fuss about his filing of a brief arguing that BJU should get the exemption despite its racist ban on interracial dating. But true to their pattern of white-washing Reagan's record on race, not one of Lott's conservative critics said a mumblin' word about the Gipper's deep personal involvement. They don't care to recall that when Lott suggested that Reagan's regime take BJU's side in a lawsuit against the Internal Revenue Service, Reagan responded, "We ought to do it." Two years later the U.S. Supreme Court in a resounding 8-to-1 decision ruled that Reagan was dead wrong and reinstated the IRS's power to deny BJU's exemption.

Republican leaders and their apologists tend to go into a frenzy of denial when members of the liberal media cabal bring up these inconvenient facts. It's that lack of candor, of course, that presents the biggest obstacle to George W. Bush's commendable and long overdue campaign to persuade more African-Americans to defect from the Democrats to the Republicans. It's doomed to fail until the GOP fesses up its past addiction to race-baiting, and makes a sincere attempt to kick the habit.
