I've been curious after your posts.
Brownback converted in 2002.

In 2006, he addressed the meeting of the new organization Christians United for Israel.

Speech to Knesset

He still won't be elected President.
Thank you very much for the information. I don't have much, beyond his opposition against fathers' rights in Kansas.
