The blue-chip Marquette Law School puts Barack Obama up in Wisconsin, 49%-46%.
That's down slightly from the president's 50%-45% lead before the Paul Ryan pick, but nevertheless, some welcome news for Obama after two polls within the last week showed Romney up 1%.
Wisconsin voters were more likely to think the Ryan pick was "excellent" (31%) than "poor" (19%), and a strong 58% said the veep selection reflected well on Romney's presidential judgement, while just 31% said it reflected poorly.
In short, people approve of the Ryan pick, but it's not enough (in this poll) to wipe away Obama's lead.
One of the reasons the president is leading? He's got a 48%/45% approval rating. Not great, but good enough.
