By Jacob Adams, The Daily Signal - On my way back from Mass recently, I walked past Alex Padilla, the uber left-wing California senator, coming out of St. Joseph’s on Capitol Hill. The incident was just the latest reminder for me that the Catholic Church is increasingly functioning as the new mainline church in American politics where left, right, and center gather to receive Christ. St. Joseph’s is located about a block away from the conservative Heritage Foundation, and a friend of mine has spotted the leader of the centrist Make America Healthy Again movement, Robert F. Kennedy Jr., at the parish as well.
