Cal Thomas: “Here’s some advice, not only for [Sen. Ted] Cruz, but for the other would-be candidates: Instead of nonstop attacks on President Obama, adopt a positive and future-oriented agenda. Cruz and the other candidates can start by considering some uplifting new videos created by Bob Woodson, president of the Center for Neighborhood Enterprise and Rep. Paul Ryan (R-WI.), who recently accompanied Woodson on a tour of some of America’s poverty pockets. They spoke with people once considered beyond redemption, but who have turned their lives around. The result is a just released seven-part online video series called ‘Comeback.’ The series highlights stories about drug addicts, alcoholics, abusers, gamblers, prostitutes and others, who with inspiration, motivation and perspiration are now inspiring others to pull themselves up and out of dire circumstances without help from the government. … Focusing on what works is better than ideological bomb-throwing, as even Hillary Clinton suggested in recent remarks. Woodson and Ryan have created something that could shift the political debate for 2016, if Cruz and the other candidates listen and get the attention of those voters who are disgusted with a dysfunctional and costly federal government.”
