Let’s pretend the Chicago Tribune poll was within the window of 2 years of looking at media bias.
____________________________________________________
Chicago Tribune Poll conducted by Market Shares Corp. June 23-27, 2004. N=1,000 adults nationwide. MoE ± 3 (total sample).
“Thinking again about the media and their news stories about politics, elected officials, and election campaigns, do you think their coverage is biased or not biased?”
....
.
Asked of respondents who answered “Biased”:
“Generally speaking, do you think the news media are mostly biased in favor of Republicans, mostly biased in favor of Democrats, or does the bias favor each party about the same?”
.
In Favor of Democrats ......... In Favor of Republicans .........
Each About The Same ......... Don’t Know
% % % %
Republicans ......... 53 ......... 4 ......... 26 ......... 2
Independents ......... 14 ......... 11 ......... 42 ......... 7
Democrats ......... 4 ......... 24 ......... 40 ......... 4

For this poll, we would subtract what the republicans view as liberal bias minus what the democrats view as conservative bias. We’d also seek to magnify any bias found by independents.
53 (pub view of dem bias) - 24 (dem view of pub bias) = 29 points of liberal bias. Independents see 14- 11 = 3 points of democrat bias. I don’t see how we could use this number to help in a calculation, but if it strikes Intrade as important, a suitable multiplier could be found. Perhaps we just add the amount of bias to the result, which yields 29 + 3 = 32 points of bias.
Since N = 1000, N/400 = 2.5
Previously, we had
MBR: 18 points of liberal bias
Skews: 19 points of liberal bias
Polling Point: 12.5 (pretending to use my data) points of liberal bias
If the contract were to expire today, it would have ONE opportunistic element, so the value would be (18 + 19 + 12.5)/4 (assuming you weight all 3 the same) + 32/4 = 20.4 points of liberal bias. The opportunistic result in this case does not push the result around heavily.

News Reporting is Perceived as Biased, though Less Agreement on Whether it is Liberal or Conservative Bias

Over six in 10 U.S. adults agree that there is bias in the reporting of news, though there is less agreement as to whether there is a liberal or conservative bias. ....
These are the results of a nationwide Harris Poll of 1,179 U.S. adults surveyed online by Harris Interactive® between June 7 and 13, 2006.
....
Interestingly, the adult public overall thinks that there is more of a liberal bias (38%) than a conservative bias (25%). While this may not be altogether surprising, the fact that the findings don’t show an even greater liberal bias is noteworthy.
Furthermore, among those who are “heavy” users of the media, a majority (54%) say that there is a liberal bias in news reporting, compared to 24 percent who say there is a conservative bias. Among “light” media users there is less of a difference, with similar numbers saying that there is a liberal bias (31%) or conservative bias (25%).
CNN viewers are split on this issue, with a third (33%) saying that there is a liberal bias and another third (32%) saying there is a conservative bias.
FOX News viewers, however, strongly feel that there is a liberal bias (69%) as compared to 12 percent who say there is a conservative bias.
.....
There is a liberal bias in the media
Republican 66 %
There is a conservative bias in the media
Democrat 37 %
Using the previous approach, 66% - 37% = 29% liberal media bias.
