In reality, she doesn't truly support Brownback, he's too conservative for her but she doesn't want to have 'rat endorsement go down as one of her last political acts.

We have more than our share of milquetoast, liberal Republicans. Whatever Brownback does, he deserves high praise for purging the moderates.
