Speaking at a press conference back home in Kansas, Sam Brownback dropped out of the presidential race today. "My yellow brick road came just short of the White House this time," he said.

Later in the event he put it more bluntly: "We're out of money."

Brownback's campaign had been hurt by a lack of fundraising success and a third-place showing behind Mike Huckabee at the Iowa Straw Poll, an indicator that Huckabee had won their two-way caucus within the caucus for Christian-right support in Iowa.
