There’s reportedly a joke going around among Iowa Republicans that Marco Rubio must be running for mayor of Ankeny, the Des Moines suburb where his sole Iowa office is located. Defying Iowa’s tradition of retail politics, Rubio also rarely holds campaign events outside of that area and is choosing to invest in television ads over staffers and offices in the state. Rubio is making a deliberate gamble that Iowans will brave the cold on his behalf this Feb. 1 simply because they saw his advertisements or debate performances on television, not because they have seen him in person or heard from his campaign.
