CBS News projects President Obama will win Wisconsin, Pennsylvania and New Hampshire. The key battleground state of Ohio is leaning toward the president.
Ohio, with 18 electoral votes, is one of the most competitive states on the map. Mr. Obama won the state by 4.6 percent in 2008. In 2004, President Bush won Ohio by 2.1 percent.
In 2008, Mr. Obama won Wisconsin by 13.9 percent. The state, which carries 10 electoral votes, hasn't gone red in a presidential election since 1984. Even with Wisconsin Rep. Paul Ryan on the ticket, Mitt Romney faced a steep challenge in his fight for the Badger State. However, the state has been a hotbed of partisan discord in recent years and Republicans saw huge gains at the state level in 2010.
New Hampshire has just four electoral votes, but it was one of the most competitive states in the nation -- it's the only state that George W. Bush won in 2000 but lost in 2004. In 2008, Mr. Obama won the Granite State by 9.6 percent.
