Did you see this establishment scam?

An unidentified Washington D.C. organization has mailed to Kentucky very conservative-looking flyers touting establishment candidates who have refused to be pinned down specifically on key issues. I'm not nearly as concerned about any possible campaign finance violation (mailing organizations should identify identify themselves) as I am curious to know why the secrecy was thought to be necessary.

Slippery establishment types posing as rock-ribbed conservatives have damaged the Republican brand enough. If you have seen a mailer like this touting your local establishment politician, please let me know.
