Whether Martin Luther said it or not, it’s still a good rule to follow. Whatever we think of Romney’s politics (to the left of what I’d like), he’s still a good, decent human being who loves America and wants what’s best for this country.
I'm not sure that the wisdom is so obvious. If the logic in the statement was self-evident, people wouldn't need to attribute Martin Luther to add credibility.
If Mitt Romney were just a pew sitter, most wouldn't be alarmed by his religion but Romney is a true-blue believer. Because most people and all Christians hold that Mormonism is a false religion with a false gospel, there is a problem voting for Mitt Romney. Either Mitt Romney is totally deceived by Mormonism or he knows that it is false religion and is actively trying to deceive people into joining. Neither is a good characteristic in a President.
All of the evidence says otherwise, Romney is not a good and decent man, he has lived the life of a self serving pathological liar and cult leader who has none of the normal love of America or of his fellow Americans.
When you look at the Romney outside of his Mormon tribe, it gets pretty nasty.
Romney has always been against conservatism and the agenda of the Christian and conservative Reagan wing of the GOP, Romney even supported, donated to, fundraised for, and voted for democrats before making the decision to register republican in October of 1993 to run for office.
Romney was repulsed by Reagan and the "good, decent" pro-life, anti gay-agenda conservatives, and changed his party registration accordingly.
How does a decent person promote abortions?
How does a decent person advance the destruction (by lies and distortions) of conservatives?
