The Catholic League has the scoop:

When in college, Mara was active in the Earlham Socialist Alliance, a group that supports the convicted cop killer Mumia Abu-Jamal and openly embraces Marxism-Leninism. After graduating, Mara spoke at rallies held by ACT-UP, the anti-Catholic group that disrupted Mass at St. Patrick's Cathedral in 1989 by spitting the Eucharist on the floor. In 2000, she practiced civil disobedience when she took to the streets of Seattle in a protest against the World Trade Organization. In 2002, she tried to shut down Washington, D.C. in a protest against the IMF and the World Bank.

. . . If Kerry continues to use religious language appropriately (and not only when speaking in the South) and embraces the millions of religious Americans that are the base of his supporters, he might just change some assumptions about the "secular" Democratic Party, and in the process, pick up a crucial constituency that could tip the balance of the election.

Ultimately, I can't separate my Christianity from my values or my values from my politics. For me, being engaged in politics is an expression of my deepest held religious beliefs -- it is about actualizing a collective commitment to protect the integrity of God's creation, it's about meeting the needs of the "least of these," and about our nation being a generous and trustworthy leader in the world. There are certainly positions taken by leading Democrats with which many Christians won't agree -- and many Christians are appalled by what they see as the exploitation of religion for political gain on the part of the Republican Party. The bottom line in applying our beliefs in the political arena is making an across-the-board assessment of who best represents the values we hold most dear.

Thanks to "Kerry Haters" for the tip.
