Dear Editor,In his March 18 Public Forum on the Tribune opinion page, Sen. Pat Roberts noted the second anniversary of the 2010 health reform act and presented his criticism of the legislation. Another second anniversary will occur on July 15 of this year. It will be two years since Sen. Roberts declared that “we” ought to replace the act with a plan that would actually lower health-care costs for all families in a column that appeared on the Tribune opinion page.
