Jim Geraghty of National Review and Greg Corombos of Radio America welcome the news that North Korea and South Korea are talking and that North Korea will participate in the Winter Olympics next month in South Korea, making it far less likely Kim Jong-Un will look to cause mischief during the games.  They also shake their heads as former Maricopa County Sheriff Joe Arpaio launches a bid for U.S. Senate in Arizona, since Arpaio is now 85 years old and lost badly in his most recent campaign.  And they roll their eyes as liberals cannot stop drooling over the (unlikely) prospect of an Oprah Winfrey presidential bid, with Van Jones even calling her the most beloved carbon-based life form on earth.
