Republican Sen. Sam Brownback abandoned his 2008 presidential bid Friday, his White House aspirations dashed by a lack of support and money.

Said the Kansas senator: "My yellow brick road came just short of the White House this time."

The conservative managed to gain the support of only 1 percent of Republicans in this month's Associated Press-Ipsos poll after peaking at 3 percent in June. Fundraising reports this week showed that his campaign was struggling financially, with $94,000 available to spend.

Brownback is expected to run for Kansas governor in 2010 when his second term expires. He has said he won't run for the Senate again.

He had previously said he would stay in the presidential race through Iowa's first-in-the-nation presidential caucuses in January but would drop out of the field if he finished worse than fourth there. Throughout the summer, Brownback spent considerable time and money in Iowa leading up to an August straw poll.

He finished third in that event, to former Massachusetts Gov. Mitt Romney and former Arkansas Gov. Mike Huckabee, in a blow to his candidacy.

Huckabee could stand to gain by Brownback's departure, especially among religious conservatives who share the two candidates' opposition to abortion and gay marriage.

Brownback, 51, is a former Kansas agriculture secretary who won a seat in the U.S. House in 1994, the same year voters angry with Democratic President Clinton swept the GOP back into congressional majorities.

Two years later, Senate Majority Leader Bob Dole resigned his seat to run for president, and Brownback captured Dole's seat. He won a full term in 1998 and was re-elected easily in 2004.
