The pro-union candidate did lose in Penn. the last time he ran. The unions are willing to cross over in the primary, so he still has a chance, but they will not in the general.

I would have happily voted for Santorum when I was a union member, just like I would have voted for Reagan.

The work of Democratic pollster Stan Greenberg is a classic study of Reagan Democrats. Greenberg analyzed white ethnic voters (largely unionized auto workers) in Macomb County, Michigan, just north of Detroit. The county voted 63 percent for John F. Kennedy in 1960, but 66 percent for Reagan in 1980. He concluded that "Reagan Democrats" no longer saw Democrats as champions of their working class aspirations, but instead saw them as working primarily for the benefit of others: the very poor, feminists, the unemployed, African Americans, Latinos, and other groups. In addition, Reagan Democrats enjoyed gains during the period of economic prosperity that coincided with the Reagan administration following the "malaise" of the Carter administration. They also supported Reagan's strong stance on national security and opposed the 1980s Democratic Party on such issues as pornography, crime, and high taxes.

The UNIONISTAS would have had to have had the “Santorum” plan in effect back in March as ONLY registered party members can vote in that parties primary. Party affiliation changes must be made 30 days prior to the Primary, and I have seen no news accounts of massive party swings in registrants.
