Santorum had gained a reputation as a polarizing figure during his first term in the Senate, but he entered the race with a large fundraising advantage and high levels of support from the political right. The contest began for Democrats with a brutal primary challenge; U.S. Congressman Klink narrowly bested State Senator Allyson Schwartz and former Lieutenant Governor nominee Tom Foley by running on the message that he was the only candidate capable to defeating the Republican. Klink was viewed as a viable choice because he was a traditional Democrat on most issues and had strong union ties but also was pro-life, which Democrats hoped would return votes to their party in the heavily Catholic but economically liberal coal regions of the state. However, enthusiasm around Klink's campaign quickly waned, as he was unable to appeal to either liberal or moderate Democrats. Santorum, in contrast, successfully balanced his national recognition on social issues with local concerns in route to a surprisingly large victory.
