Your numbers are far off.
Santorum is winning Reagan Democrats in Northern Wisconsin (Obama won most of these counties in 2008). These are heavily white, working class voters. This includes Brown County (Green Bay).
Santorum is also slightly winning Dane County (Madison), largely because he is very strong with younger voters (UW-Madison).
If you think that 4% of voters can flip major metropolitan counties, you are very mistaken.
Never mind that Michael Moore told people to vote for St Rick during the Michigan primary.. Also I’m seeing a lot Democrats advocating to vote for St Rick.. Not talking about the Reagan Democrats either.. Also the Reagan Democrats is just about gone..
Santorum is winning Reagan Democrats
Bahahahaha! The “Reagan Democrats” became Republicans 25 years ago. The Democrats voting for Santorum are big government big labor Democrats that are dissatisfied with Obama.
Romney now only needs 42% of the remaining Delegates and since he already has 58% of the delegates to date, that number is realistic. It is what it is. Reality does not choose sides.
