No media bias whatsoever. In its classic "fair and balanced" tradition, CBS slanted in favor of Democrats its poll that found Bush has a 34 percent approval rating and a 59 percent disapproval rating, an all-time high for a CBS poll. On the bottom of the PDF version of the poll (page 18) it says how many Democrats versus Republicans were contacted. "Total Republicans" contacted: 272 unweighted and 289 weighted. "Total Democrats" contacted: 409 unweighted and 381 weighted. "Total Independents" contacted: 337 unweighted and 348 weighted.
