Sarah Palin in a recent interview expressed support for an amendment to the U.S. constitution to ban gay marriage. The only problem is that John McCain once described this position as “antithetical in every way to the core philosophy of Republicans.” McCain has repeatedly said he is a federalist and prefers each state to make their own decision on the issue of gay marriage. No wonder the McCain campaign doesn’t want Palin to give interviews. (Palin has also disagreed with McCain on drilling in the Arctic National Wildlife Refuge, global warming, cross-border raids into Pakistan, and whether abortion should be permitted in cases of rap_ and incest.) Palin is drawing bigger crowds than McCain, and it seems like she is throwing McCain under the bus, setting the stage for a run for president in 2012. Democrats hope she succeeds.
