FrumForum's Tim Mak gets hold of Speaker John Boehner's endorsement letter of Maria Cino for RNC chair:

I respect that the choice of RNC Chairman is yours alone to make. But having spent the last two years traveling the country to meet with activists, candidates, donors and voters to help elect Republicans, I hope you will permit me to make some observations about that choice…

I have worked closely with Maria for almost twenty years, during which time she turned around the NRCC to usher in the first Republican majority in the House in 40 years. She served as CEO of the 2008 National Convention, which I chaired, and made it into one of the most successful in party history. I have learned firsthand that she is an unparalleled fundraiser and a very efficient manager of resources. She’s also exceptionally politically savvy and knows what it takes to win.
