In this Wednesday, April 16, 2014 file photo, Sen. Kay Hagan, D-N.C., listens during an appearance in Durham, N.C. The Democratic Party's control of the U.S. Senate after the general election in November could lie in the fortunes of female candidates and the deep-pocketed donors, like former New York Mayor Michael Bloomberg, who are sending piles of cash their way. Hagan in North Carolina and Jeanne Shaheen in New Hampshire face heavy outside spending but have Emily's List backing. (AP Photo/Gerry Broome, File)
