Democrats are looking to Baldwin to stem a long and deep losing streak that dates back to 2010 when Republicans took control of both houses of the Legislature, Scott Walker was elected governor and tea party favorite Ron Johnson knocked off incumbent Sen. Russ Feingold. (AP Photo/Scott Bauer, File)
