Wisconsin which has been a reliably blue state in Presidential elections is currently very close. According to the newest CNN/ORC poll of Wisconsin, President Obama has just a four point lead over Mitt Romney among registered voters.
Barack Obama 49%
Mitt Romney 45%
No Opinion 1%
It is possible that picking Wisconsin native Paul Ryan as his running mate has slightly improved Romney’s standing in the state but if the Ryan pick did help the improvement ii ts so modest it will probably require multiple polls to verify that it even happened. Other recent polls of the state before the selection of Ryan found very similar results. A Marquette poll of registered voters from early August found Obama leading by seven points, and a Quinnipiac poll of likely voters found Obama leading by six. It is possible the small improvement is the result of picking Ryan, the result of other election factors, or simply normal functions within the margin of error.
Early indicators are that the selection of Paul Ryan produced basically no national bump and at best only a small bump in his home state that is not enough to close the gap with Obama in Wisconsin. So far there seems to have been little upside in the polling for the Romney campaign in selecting Ryan, although there is a good chance Ryan’s fundraising skills and appeal for conservatives could really improve the campaign haul for this month.
