Following the earlier shot taken by presidential candidate Sen. Sam Brownback (R-Kan.) at rival Mitt Romney (R-Mass.) over abortion, a post appeared on the My Man Mitt blog calling Brownback a “bottom feeding candidate” and a “bozo” who “is about as exciting as a trip to the proctologist.” Harsh.

The post was written by Jason Bonham, a Vice Chairman of Romney’s National Faith and Values Steering Committee. Considering the language Bonham used, he may have forgotten a few Commandments.

And the Brownback campaign has just fired back:

As you know, Senator Brownback has made extraordinary progress in consolidating support from both fiscal and social conservatives in the crucial straw poll and caucus state of Iowa. In addition, our support in the early primary states of New Hampshire and South Carolina continues to grow daily, and a national movement of conservatives is quickly growing in support of Senator Brownback and his vision and agenda for America.

It comes as no surprise that an opposing campaign would stoop to levels of desperation and personal attack in order to try and stop our growing momentum. But unfortunately, that is exactly what the Mitt Romney for President campaign has done.

…

While other campaigns condone personal, vicious attacks, our campaign will continue to fight for what you want: Senator Brownback and his conservative values in the White House. [Friends of Sam Brownback Press Release]

This thing is getting brutal. And it’s only just beginning…
