LE MARS, Iowa — Rick Perry’s early, hands-on approach in Iowa contrasts with the 2016 presidential prospect’s failed bid four years ago, when he entered the race relatively late and stumbled in the debates. The former Texas governor says he has more policy knowledge now and more time for the early states. “Nobody came to Iowa more in 2014 than I did,” Perry said after speaking to about 20 people at a Pizza Ranch in Sioux Center this past week.
