Agree - this is bad move - and really makes no sense that she would do this and the Roberts endorsement during the same week.

Sort of a counter balance?

They hold a ‘jungle primary” in November in lieu of a general election, with the two top vote-getters advancing to a runoff in December unless one of them somehow pulls a clear majority.

No one thinks Landrieu is getting 51 percent on the first vote, so even if Palin drives a chunk of tea partiers away from Cassidy and towards Maness, Cassidy’s still going to be in the runoff with Landrieu. Palin might even endorse him at that point in the name of party unity, just as she has Pat Roberts in Kansas.

From the article:

So she’s going to bat for him (Cassidy) but also for the longshot Maness to reassure grassroots righties that, per Maness’s campaign theme, she’s “one of us.” And as I say, it may well be that she ends up endorsing Cassidy anyway before the runoff once Maness is out of the picture.

Is Maness the Robertsons' favorite?
