Obama won the state of Wisconsin with 52.83% of the vote to Romney's 45.89%, a 6.94% margin of victory.[2] While this represented half the victory margin of Obama's 13.91% win in 2008, when he won 59 of 72 counties and 7 of 8 congressional districts, it was still a better performance than that of John Kerry's 0.38% margin in 2004 or Al Gore's 0.22% margin in 2000. Obama's win was also surprisingly comfortable in spite of the fact that Wisconsin was the home state of Republican Vice Presidential nominee Paul Ryan, making him the first Republican Vice Presidential nominee to lose their home state since Jack Kemp lost New York in 1996. Obama's win was attributed to victories in Milwaukee, the state's largest city; Madison, the state capital; northeastern Wisconsin; and the Driftless Region. Romney's strength was concentrated in the loyally Republican Milwaukee suburbs, particularly the WOW counties (Ozaukee, Washington, and Waukesha), where he carried a combined 67.03% of the vote to Obama's 32.00%. He also flipped 24 counties in the Northeast and Central Plain regions, though most of them were rural and therefore insufficient to overcome Obama's aforementioned victories.[3][4]
As of 2020, this is the last time the Democratic presidential nominee won the following counties: Adams, Buffalo, Columbia, Crawford, Dunn, Forest, Grant, Jackson, Juneau, Kenosha, Lafayette, Lincoln, Marquette, Pepin, Price, Racine, Richland, Sawyer, Trempealeau, Vernon, and Winnebago. This is also the most recent cycle in which a Republican won Waukeusha county, a traditionally Republican stronghold in the state, with more than 65% of its votes. This is also the last time a candidate of either party won Wisconsin with more than 50% of the vote as well as the last time Wisconsin voted more Democratic than the nation as a whole.
Primaries
Democratic primary
President Barack Obama ran unopposed in the Democratic Primary, winning 293,914 votes, or 97.89%. Uncommitted ballots received 5,092 votes, or 1.89% of the vote, while 849 votes, 0.28%, were scattered. 111 delegates, all of which were pledged to Obama were sent to the 2012 Democratic National Convention in Charlotte, North Carolina.[5]
Although Republican Vice Presidential nominee Paul Ryan was from Wisconsin, representing the 1st district in Congress, the Republican Party lost by around a seven-point margin, which was, albeit an improved loss from Obama's landslide 13.91% margin in 2008,[8] a crucial loss.
