I said in a previous article that I did not have any exact figures on the uneven distriubtion of media coverage between the two candidates. Well we do now, and as I had predicted (well you didn't exactly need a crystal ball), it is a heavily skewed picture.
By a margin of 76% to 11% respondents in Pew's weekly News Interest Index survey named Obama over McCain as the candidate they have heard the most about in recent days.
But the same poll also shows that the Democratic candidate's media dominance may not be working in his favor. Close to half (48%) of Pew's interviewees went on to say that they have been hearing too much about Obama lately. And by a slight, but statistically significant margin - 22% to 16% - people say that recently they have a less rather than more favorable view of the putative Democratic nominee.
In the advertising stakes, while Obama has dominated McCain as the candidate citizens say they have heard the most about in the news, roughly equal numbers say that they are aware of commercials on behalf of each candidate. About six-in-ten have seen commercials for both candidates. Most of those who are aware of Obama's commercials say they are mostly positive messages about the candidate (38%), while fewer (13%) characterize them as negative messages about McCain. The balance of opinion about McCain's commercials is the opposite - a plurality (31%) sees them as negative messages about his opponent, with fewer (19%) describing them as positive ads.
There is surprising partisan agreement about the campaign commercials of both candidates. On balance, both Republicans and Democrats think Obama's commercials have been mostly positive. And pluralities of both Republicans and Democrats say McCain's ads are mostly negative. Nonetheless Democrats are more likely than others to say Obama's commercials are positive, and Republicans are less likely to characterize McCain's ads as negative.
