As a Christian, I'm always curious when someone starts a thread implying a Christian rationale for voting for Trump, but it always ends up being a vote out of spite, which to be fair is famously the missing third Great Commandment--love God, love your neighbor, and be spiteful.
I'm a theologically conservative Christian and a registered Democrat (Philly has closed primaries for local elections)
In 2012, I voted for Romney
In 2016, I voted for Clinton
In 2020, I left it blank
This year, I voted for Trump
