Louisiana Gov. Bobby Jindal has spent considerable time in Iowa since launching his campaign for president — pledging to appear in each of the state’s 99 counties.

Jindal’s campaign has made Iowa central to its strategy in the GOP nominating process and has touted high favorability ratings as an indicator of his potential for success there. The Iowa caucus is Feb. 1.

An NBC/Marist poll out this week found Jindal tied with U.S. Sens. Ted Cruz and Marco Rubio at 4 percent support among likely caucus-goers surveyed. Jindal’s support is up from 1 percent in the same poll in July.

Meanwhile, a Gravis poll conducted during the same period put Jindal at 5.2 percent — just ahead of Carley Fiorina.

Donald Trump topped both polls.
