Kansas Sen. Sam Brownback said he needs to finish at least fourth in Iowa.
WASHINGTON (CNN) - Sen. Sam Brownback, R-Kansas, said in an on-line discussion Wednesday he would drop out of the race for the White House if he did not finish in the top four in Iowa.
In the question and answer session on The Washington Post, a person asked the Kansas Republican, "Is it true that you will drop out of the race if you don't finish in the top 4 in Iowa?"
"That is correct,” Brownback responded. “I need to finish in that group to move on forward."
