He did attend Church throughout his life (I think) . . . not as much in Washington because it is such a to do for a President to go to church. Disrupts the congregation. He wrote and spoke a lot about it; he certainly didn’t hide that he was a Christian.
I don’t even know what the label evangelical really means. Every Christian is told in the Bible to evangelize. So every Christian is evangelical. Every Christian is born again (same thing — Christ said we must all be born again when he spoke to Nicodemus). Most people think of themselves as Presbyterian, or Baptist, or Catholic, or Pentacostal . . .
Well then maybe instead of saying, "I couldn't vote for a Mormon or any other candidate who wasn't an Evanglical or Catholic Christian," you should have just said I won't vote for a non-Christian.
Not all Christians consider themselves Evangelicals, primarily people who go to non-denominational churches.
