After a fierce battle between Obama and Clinton in the Copper State, Obama shines.  The Senator from Illinois wins Wisconsin by a significant margin of 58% to 41%.  The Clinton campaign was hoping to reduce the victory margin to a single digit win but Obama won by 17 points.  Wisconsin has 74 elected delegates and 18 superdelegates available, totaling 92 delegates up for grabs in the state.  Wisconsin was true blue but has shown a tendency to swing or be purple due to the influx of progressives in the state.  The Badger State is also a critical win for Democrats in November.  Having said all of that, the state is also tailor made for Hillary Clinton.  White working class voters make up the majority of the electorate.  The significance of this Obama victory is not missed because the Senator has again broadened his coalition.  The white women vote was split almost evenly between Clinton and Obama with Clinton winning the group 53% to Obama’s 45%.  Obama won white men 62% to Clinton’s 36% and made inroads with working class voters increasing his percentage to 48% to Clinton’s 51%.  Clinton did win with three other groups: seniors, voters with less than a college education, and catholic voters.  The Illinois Senator won 63% of all voters who decided in the last month.  As to the issues, Obama won on healthcare, the war in Iraq, the economy, and electability.  According to exit polls, seven in ten voters believe that international trade takes jobs from the United States.  The North American Free Trade Agreement may have hurt Hillary in this regard because many states like Wisconsin and Ohio have been deindustrialized because of the Agreement.  It is significant that Bill Clinton was the primary force behind the passage of NAFTA.  Another contributing factor to the outcome of the Wisconsin contest is same day voter registration, citizens can register to vote and actually vote on election day.  In addition, Wisconsin is an open primary where independents and republicans vote in the democratic primary, two groups that tend to go for Obama.  The exit polls also revealed the following facts about Wisconsin voters: 43% thought the economy is the most important issue;  29% are concerned about the war in Iraq;  25% are concerned with healthcare;  90% of the voters thought the economy is not doing well;  17% of voters were first time primary voters;  27% were independent voters; 59% of the voters had income levels over $50,000. McCain also won in Wisconsin and Washington state.  McCain will receive the 40 delegates from Wisconsin and 19 delegates from Washington state.
