ABC News' Teddy Davis reports: Michael Steele's political standing as chairman of the Republican National Committee is continuing to deteriorate. Alex Castellanos, a Republican media consultant who has been serving as an unpaid top adviser to the RNC, suggested on CNN Tuesday that Steele needs to step down as party chairman. "I think a change in direction now at this point would do the party good," said Castellanos. Castellanos suggested that Steele needs to go because the RNC chairman has lost the support of congressional leaders and, most importantly, major donors. "Chairman Steele, I think, has lost the support of two important constituencies in the Republican Party: one is our . . . leaders on the Hill . . . but more importantly, he's lost the support of a lot of our major donors, the donors who provide the money, the lifeblood, the oxygen the Republican Party needs to succeed on its mission to take back control of the House." "This is nothing personal," Castellanos continued. "This is about a party that has a cause, and that is, rescuing this country from bankruptcy. We have a responsibility as Republicans, I think, to provide the support that our candidates need to do that. And right now, I don't think that you're seeing a lot of that money. [It] is frozen, it's not coming into the party, and perhaps a change in leadership here would thaw that and allow that support to flow." According to a Republican close to the RNC, Castellanos’ advisory role began to decline in January of this year. During Tuesday’s interview on CNN, the veteran strategist made clear that he is ending his role as an unpaid adviser to the RNC. “Wolf, I've lost my ability to be of service, I think, to the RNC, and that's happened for quite a while,” said Castellanos.
