A Paul family affair: Rand to stump for Ron in Iowa

(CNN) - Republican Sen. Rand Paul of Kentucky will head to the first-in-the-nation caucus state of Iowa later this month to campaign for his father's bid for the White House.

The younger Paul's Iowa swing will come just before the Ames, Iowa, straw poll. GOP Rep. Ron Paul of Texas, who's making his third run for the presidency, is putting a lot of money and effort into doing well in the crucial straw poll.
