Johnston didn't take a break from bashing the bee-hived politician when her name came up. He said Palin has little room to criticize his decision, as she abandoned the Alaskan governorship to pursue a lucrative book offer. He said that she started discussing leaving her post in Alaska upon gaining new heights of fame, following her nomination as the Republican party's vice presidential candidate during the summer of 2008.
