Its a false story. Wolf has confirmed there is no such endorsement on the cards
Wolf's "confirmations" have as much credibility as Dick Morris' predictions. I wouldn't put it past Wolf to endorse Orman, either officially (in public so he can play kingsmaker and make himself look important) or unofficially (by undermining Roberts behind the scenes and talking up Orman by praising what an "effective" candidate he is and how he'd make a good Senator, etc.)
He certainly has ACTED like he wants the KS RATs to win over the past few weeks, given all his snarky KS GOP bashing. Shades of how "conservative" Ray LaThug never "officially" endorsed Obama in 2004 or 2008, but he did everything he could to bash conservative Republicans and heap praise on Obama as an articulate suave consensus-builder. He was rewarded for his treason with a cushy job as Transportation Secretary in the Obama administration.
If Wolf wants to set the record straight that he's NOT helping Orman, he should tell his fan club to stop throwing a temper tantrum and cast their votes for a reliably conservative Senator. Period.
In any case, how are the actions of Wolf supporters vowing to oppose Roberts any different than the actions of uber RINOs Mike Castle or Dede Scozzafava? Can't beat a proven conservative in the primary, so out of spite they root for a marxist RAT in the general election to "teach the GOP a lesson".
