WASHINGTON (AP) - Kansas Senator Sam Brownback appears to be ready to quit the Republican presidential race.

He's expected to announce a decision tomorrow, and people close to him say he's dropping out.

One person says the senator has enjoyed campaigning and meeting new people, but it's the money that's torpedoing his candidacy.

Brownback has been considered a longshot and had trouble raising money. He has brought in more than 4 million dollars over the course of the campaign, and it's been tailing off in recent months. In the third quarter of this year, he brought in his lowest quarterly amount with a little more than $800,000.

Brownback, who is in his second term, had said he would serve no more than two terms in Senate. He is widely expected to seek the Kansas governor's office in 2010.
