The only ads I've seen have been for people running local townie positions accusing the incumbent, who in most other states would be considered as far right as you can get, of being too liberal.
Unfortunately the ultra conservative/tea partiers have found out what most moderates in both parties knew for a very long time. Incumbents rarely lose to a challenger in a general election. It's much, much easier to win a primary where turnout will be low.
That's why you always see the real derp like state constitutional amendments for this or against that in off-year spring elections.
Of course there would have bee one less tea party member in the KS senate if Roger Reitz and Joe Knopp could have settled their pissing match without handing Reader an easy win.
