Pointing to his support of family values, an Iowa couple says they will lead an effort to support Kansas Senator Sam Brownback's Presidential bid.

Mark and Marie Scherbaum will chair the "Homeschoolers for Brownback Coalition." Brownback has been heavily campaigning in Iowa in advance of the August Republican straw poll.

"Sam Brownback understands the unique role that parents play in the lives of their children and he believes that parents should have the freedom to homeschool their children," Marie Scherbaum said in a statment.

In recent weeks Senator Brownback has announced Iowa Catholics for Brownback and his Iowa Faith and Family Leadership Committee.
