In the democratic primaries there was a 9% Republican precipitation out
of a 1,098,802 total democratic primary votes. So that means 98,892 are
republican leaning, and of those 72% voted for Obama which gives us
71,202 republicans that voted for Obama. The entire republican vote in
Wisconsin was 403,568 if we take the named republicans (73%) out of
that, we have 294,605 republicans that voted in the republican primary.
Total republicans voting in Wisconsin is 365,807, and 98,892 of those
voted for Obama. That's 27% of the republican base voting for Obama.
This does not bode well for the republicans in November.

And the
flip side? Lets start with the number of democrats in the republican
primary which is 5% of 294,605 or 14,730. They don't even have info for
results that small. Even if all 20,178 voters voted for Clinton that
would only make up .01 democratic primary voters. Again the republicans
have to be worried.
