Gallup has just released some interesting numbers on the differences in approval levels for top political figures among whites and minorities. The survey breaks down the numbers between non-Hispanic whites, blacks, and Hispanics.

George W. Bush’s approval rating among whites is 32 percent, with 65 percent disapproval. Among blacks, the approve-disapprove number is 8-87. Among Hispanics, it is 29-63. (The Hispanic approval rating, by the way, is down from 38 percent a year ago, which could indicate that Bush’s efforts on behalf of immigration reform haven’t done him much good with Hispanics, or it could be that his approval rating with them would have been even lower without his reform effort.)

The Gallup numbers for the Democratic presidential candidates are fascinating. The headline is: Hillary Clinton is more popular with blacks than Barack Obama. Eighty-four percent of blacks surveyed by Gallup have a favorable opinion of Sen. Clinton, versus 10 percent unfavorable. Among whites, her numbers are 41-57, and among Hispanics, she is 63-20.

Obama’s favorable/unfavorable rating among blacks is 68-8, with 16 percent saying they’ve never heard of him. Even if every one of those 16 percent eventually had a favorable view of him, he wouldn’t surpass Sen. Clinton. Among whites, Obama is 53-31, and among Hispanics, he is 33-13 (45 percent of Hispanics say they’ve never heard of him.)

John Edwards’ numbers among blacks are 48-15, with 25 percent never having heard of him. Among whites, he is 45-38, and among Hispanics he is 35-16, with 37 percent never having heard of him.

Among Republicans, the candidate who has the highest favorable rating among blacks is — make sure you’re sitting down, New Yorkers — Rudy Giuliani. His favorable/unfavorable among blacks is 34-35, with 20 percent never having heard of him. Among whites, Giuliani is 64-27, and among Hispanics, he is 46-16, with 28 percent never having heard of him.

John McCain is 49-35 among whites, 26-33 among blacks, and 31-22 among Hispanics. (31 percent of Hispanics and 24 percent of blacks say they’ve never heard of him.) Mitt Romney is 29-28 among whites, 11-21 among blacks, and 12-9 among Hispanics. (The percentages who have never heard of him are 27, 56, and 68, respectively.) And Fred Thompson is 35-11 among whites, 15-17 among blacks, and 13-8 among Hispanics. (The percentages of who have never heard of him are 40, 58, and 70.)
