Well, yeah, It’s how you live your life. True for all faiths as well.
I hope you understood I mean this in the political sense.
When with other people it’s fine to discuss being a Christian, but it has to be done in a non pushy manner.
As a politician though, you mention your faith once, and then you’re on the record. Mentioning it over and over and playing it up that you’ll get the Christian vote, is a big mistake IMO.
When Cruz lost the South, he had set himself up. It would have been bad if it lost it anyway, but after professing his faith and then thinking it was all sewn up, big mistake IMO.
