Seriously, that made me laugh.
I’m certain that you understand my point.
However if someone chooses to vote solely on religion, or worse yet, tells someone else how they should be voting based on religion, I remain free to consider such actions misguided, and to state my opinion on the matter publicly.
If it were to more accurately state that conservative Christians (of ALL denominations) vote for Cruz, he will be the nominee, then the premise would much more sense.
Whether the candidate himself shares the person's faith is immaterial. I've seen numerous self-proclaimed "Christian" candidates whose record and values are anything but, and numerous non-Christian candidates whose record and values are ideal.
In short, voting for someone because he happens to be a member of the same religion as you is a bad idea. But voting for someone because he happens to share the same VALUES as you is highly recommended.
