Sam Brownback to Withdraw

According to this AP article:

Republican Sen. Sam Brownback, the Kansas conservative who struggled to raise money and gain recognition in the 2008 presidential campaign, will drop out on Friday, people close to him said Thursday.

This announcement comes on the heels of this Christianity Today Interview, posted today, that says in part:

CT: Do you see abortion as a significant part of this campaign?

SB: I see it as the lead moral issue of our day, just like slavery was the lead moral issue 150 years ago.

CT: Why do you think evangelicals are not rallying behind you in light of your pro-life stance?

SB: There's a combination of things. One is that I am not as highly visible as some of the other candidates. Second, we haven't raised the amount of funds that some of other candidates have. I think there is a general position on our side that people are watching and waiting. They're waiting to see the candidates run for a while before [they] decide. It is very early. Some people are tired, just of politics, saying, "I'm just weary."

CT: At what point would you withdraw from the race?

SB: I'm not going to. I have said we need to finish in the top four in the Iowa caucuses. We just haven't gotten hardly any media coverage, particularly if you compare me to Hilary Clinton and Barack Obama. We have got to crack through that, but the only way to do that is to perform, perform in the states.
