Walker was taken out by the GOPe long before Iowa, in case you forgot.
He was taken out by Trump as I explained in my last post to you. He was in the lead at the end of June, Trump passed him by the first debate on August 6th, and Walker faded quickly as Carson and Cruz rode on Trump’s outsider coattails.
Before Trump made waves, Walker was running as the D.C. outsider, and doing it quite successfully.
