Rubio gaining steam heading into Iowa caucuses
Republican Marco Rubio is sprinting toward the Iowa caucuses, avoiding direct confrontations with his opponents and instead, projecting a vision that looks more toward the general election.
Polls show Ted Cruz and Donald Trump ahead in Iowa, but Rubio has been gaining.
He's told supporters "We are not just picking a political party, we are picking the very identity of our nation."
It's part of the 44-year old Rubio's effort to cast himself as part of a new generation of conservative Republicans. while characterizing Democratic front-runner Hillary Clinton as an embodiment of a longstanding partisan gridlock.
