From the Hill:

A GOP source close to Boehner told The Hill, “The surest sign that Mr. Blunt’s camp doesn’t have high confidence in his count is the obvious one — he has not stepped down from the whip’s post”
But Blunt’s spokeswoman, Burson Taylor, said that Blunt expects that there will be a vote to fill the whip’s job.
A House source close to Blunt said the lawmaker thinks it’s important to maintain “regular order” as much as possible in this situation.
“This was a special election for a single vacancy created by Mr. [Tom] DeLay [R-Texas], until Mr. Shadegg stepped down too. If the members decide they really want to elect a full slate of leaders, they’ll sign the petition and vote to do so,” the source added.
