Senator Ted Cruz, a Republican from Texas, speaks during the Iowa Freedom Summit in Des Moines, Iowa, U.S., on Saturday, Jan. 24, 2015. The talent show that is a presidential campaign began in earnest Saturday as more than 1,200 Republican activists, who probably will vote in Iowa’s caucuses, packed into a historic Des Moines theater to see and hear from a parade of their party’s prospective entries.
