Rasmussen Poll Exhibits Anti-Ron Paul Bias

Rasmussen's "Daily Presidential Tracking Poll" exhibits anti-Ron Paul bias today.  This is how the poll describes its survey:

The Rasmussen Reports daily Presidential Tracking Poll for Monday shows Mitt Romney earning 47% of the vote while President Obama picks up support from 45%. Four percent (4%) would vote for a third party candidate, while three percent (3%) are undecided.

Much of the results of a survey depend on how you ask the questions.  For example, if you ask car buyers, "Do you prefer a Lexus, a Cadillac, or another car," then the results will not be the same as when you ask them, "Do you prefer a Lexus, a Cadillac, or a Rolls Royce."  Rasmussen asks its sample the first question.  The correct question is this:  "Who would you vote for in a three-way election: Obama, Romney, or Ron Paul."

I know that Rasmussen knows this perfectly well. The bias is not because of incompetence.
