WI: Rasmussen: Walker takes narrow lead

[Vega]

Backed up by Marquette. Is Rass turning around?

Ras is erratic and not precise now that Scott's left, but it does not appear to have much of an R house effect this year.  Ironically, a biased poll that is more precise has more predictive value than a less precise one , but we'll see how the polls shake out in a couple months.

Rass tends to vary - they aren't a polling company you can set your watch to.
