Media polling is beyond ridiculous. The same bias exists within any media poll as reflected within all other content aspects provided by the broadcast or publication.

The timing of media polling is also well beyond predictable. To generate news-worthy headlines they always push polling results around key dates; in this example on the eve of the first general election presidential debate.

ABC/WaPo release a poll today (pdf here) containing all the previous elements found in their prior ideological agenda polls. The selection of party affiliation responses is silly.

The most current national survey of party affiliation shows Democrat party registration is D+4 –SEE HERE– nationally. However, for their needs, ABC/WaPo use D+10:

However, the good news is: even with that ridiculous +10 skew ABC/WaPo can only manage a 2 point Clinton lead: 46/44
