Some conservative media outlets used the Rasmussen polling to prop up a narrative in the final days of the campaign that Romney had momentum and a good chance of winning the White House.
Averages of all the big polls tended to show otherwise — giving Obama a razor-thin margin in the popular vote and small but consistent leads in most of the battleground states that would decide the election.
In many of those battlegrounds, Rasmussen’s preelection surveys stood out. Other polls mostly showed Obama with a lead, sometimes larger than the polls’ margins of error.
Rasmussen has drawn scrutiny before because it employs automated surveys that do not reach mobile phones, which more and more Americans use as their primary form of communication.
The pollster also “weights” results to try to predict the party identification of the electorate. Other pollsters frown on this approach, saying one of the primary functions of the polls is to assess whether voters consider themselves Democrats, Republicans, members of some other party or no party.
