I’d apply that eleventh commandment to conservatives particularly. The moniker “Republican” is wasted on the Uniparty.
As for a leader for the country, the Founding Fathers put the greatest value on character; and it’s a shame not too many nominal conservatives do not make mention of Deuteronomy 17:15.
You think this presidential race is nasty? The Founding Fathers had it beat. In the race between John Adams and Thomas Jefferson for president in 1800, Jefferson called Adams “a blind, bald, crippled, toothless man who is a hideous hermaphroditic character with neither the force and fitness of a man, nor the gentleness and sensibility of a woman.”
In turn, Adams called Jefferson “a mean-spirited, low-lived fellow, the son of a half-breed Indian squaw, sired by a Virginia mulatto father.”
Compare these with the relative politeness of today.
