Just to expand a bit on what Alexander noted here, to the extent that primary voters consider both electability and values when choosing their candidates, reporters should take it upon themselves to provide an accurate assessment of ... the candidate's actual values!
If, for instance, an Iowan is considering a vote for Obama on electability grounds, then that Iowan should also know that Obama has opted out of partisanship and adopted some flawed conservative rhetoric on social security and healthcare (and, to be fair, that he's also established a formidable team of foreign policy advisers).
Likewise, if an Iowan would only support Hillary Clinton if she seemed more electable, then they should probably know that, in the Senate, she's shown a fairly impressive ability to win over the very people who tend to attack her from the right.
It's the sort of values-oriented information that few know, but that would, if reported, probably impact the electability statistics we've come to love so much.
