It has been just over four weeks since the new MSNBC lineup took shape on March 17. TVNewser took a look at the four weeks of ratings (March 17-April 11) since the launch of David Gregory's Race for the White House and the 10pmET reair of Countdown with Keith Olbermann. We compared them to the previous four weeks (February 18-March 14).

The 6pmET, previously occupied by Tucker Carlson and now by Race, has seen a slight improvement in the A25-54 demo (136K vs. 152K) and a large improvement in Total Viewers (392K vs. 504K). Each period included 19 shows.

At 10pmET, the repeat of Countdown replaced the first hour of the doc block. The decision has not helped the ratings in either category.

The Countdown re-air has averaged 175K in the demo and 436K in Total Viewers (19 shows). The previous four weeks saw the doc block average 261K in the demo and 532K in Total Viewers (16 shows).
