Here is complete video of Sen. Marco Rubio speaking in Iowa tonight at a birthday event for Iowa Gov. Terry Branstad. Many believe this trip by Rubio to Iowa is his opening foray into the 2016 GOP Presidential Nomination race. Rubio made the case for taking the conservative message of why Free Enterprise and Limited Government are the principles to give Americans a shot at the best future they can possibly have. Rubio urged conservatives to not give up on taking that message to the country in a positive and compassionate way.
