We are a nation swallowed by party, and in no place is this more evident than in the refusal of Republicans -- both the politicians and the people -- to come eyeball-to-eyeball with the Russian threat upon our presidential election.
Strip away party loyalty, and a person looks at the danger of what might have happened, and says, "Investigate, of course investigate." But a person blinded by love of party will not concede the danger. "There is no evidence," they shout. "Get over it; the election is finished. Quit with the conspiracy theories." They are not concerned with whether Russia interfered, only it matters to them that their man won.
Party loyalty Trumps national security.
