The campaign of Rep. Todd Tiahrt, R-Goddard, looked childish and desperate in sending out an e-mail falsely claiming that Senate rival Rep. Jerry Moran, R-Hays, had been endorsed by the Communist Party USA. But as Washburn University political science professor Robert Beatty hoped, perhaps the incident may lead to an intelligent discussion about U.S. policy. Perhaps — though probably not. As Moran correctly argues, decades of U.S. embargoes haven't brought an end to communist rule in Cuba and actually may have helped prop it up. Lifting some trade and travel bans to Cuba would benefit Kansas farmers and could help spread democracy.
