The reporter writes a story about the evasiveness and potential implications of a future switch. Suddenly the spokesman calls in a clarification stating she won't switch.
All this sounds like good journalism to me - not taking an evasive answer on face value, but the TPM comment section is full of attacks on the journalist for not being "objective" and simply reporting the answer. There are a few who defend the journalist, but it generally reads just like something you'd see on a rightwing website (maybe better grammar though).
The left can have as much trouble as the right with seeing past their own biases.
