We are commanded to righteously judge others, from church leaders and members to politicians, by using the Spirit, the scriptures and the person's fruits.Andrew52 wrote: "This topic of judging others could actually be taught in a two-word sermon. Stop it!" -Dieter F. Uchtdorf
Mr. Romney is a worthy priesthood holder.
Joseph Smith changed 'judge not' to 'judge not unrighteously'. So 'stop it' does not apply to 'judging', as long as we do it righteously.
Just because Mr. Romney was ordained to the Priesthood at one time, doesn't mean he is now a Priesthood 'holder'.
Only righteous living and 'honoring the Constitution' can maintain his Priesthood.
