It is Scott Walker:

Charles G. and David H. Koch, the influential and big-spending conservative donors, appear to have a favorite in the race for the Republican presidential nomination: Gov. Scott Walker of Wisconsin.

On Monday, at a fund-raising event in Manhattan for the New York State Republican Party, David Koch told donors that he and his brother, who oversee one of the biggest private political organizations in the country, believed that Mr. Walker would be the Republican nominee.

“When the primaries are over and Scott Walker gets the nomination,” Mr. Koch told the crowd, the billionaire brothers would support him, according to a spokeswoman. The remark drew laughter and applause from the audience of fellow donors and Republican activists, who had come to hear Mr. Walker speak earlier at the event, held at the Union League Club.

Two people who attended the event said they heard Mr. Koch go even further, indicating that Mr. Walker should be the Republican nominee. A spokeswoman disputed that wording, saying that Mr. Koch had pledged to remain officially neutral during the primary campaign.

But Mr. Koch’s remark left little doubt among attendees of where his heart is, and could effectively end one of the most closely watched contests in the “invisible primary,” a period where candidates crisscross the country seeking not the support of voters but the blessing of their party’s biggest donors and fund-raisers.

Not surprising.

The Kochs don’t want to waste money, and Scotty, goggle-eyed homunculus hired by Koch Industries to manage its Midwest subsidiary formerly known as the state of Wisconsin,^* is already bought and paid for.
