Survey USA has a new poll in Indiana and it shows Hillary Clinton with a nine-point lead over Barack Obama (52%-43%), a contrast to the neck-and-neck data we saw late last week. However, it's important to note that the nine-point margin represents significant tightening since Survey USA's previous poll in the state, which was released on April 14 and showed Clinton up by 16 points.

Speaking of tightening, a new Public Policy Polling survey in North Carolina shows Obama's lead over Clinton at 12 points (51%-39%), as compared to his 25-point edge in the same poll last week.

Meanwhile, our neighbors to the North also released some interesting data today. A University of Wisconsin Badger poll surveyed the two possible general election matchups and found that Obama leads John McCain by four points (47%-43%), while Clinton trails him by six points (41%-47%). This type of data only bolsters the argument that Obama is viable in a wider range of states than Clinton.
