House Elections Host Bob Edwards talks to U.S. Rep. Tom Davis (R-VA) and U.S. Rep. Nita Lowey (D-NY) about the fall House elections. Davis and Lowey chair their respective parties' House campaign committees, which dispense funds and advice to candidates. Across the country, candidates from both parties are back in their districts for the July 4 holiday, campaigning. To retake control of the House from the Republicans, Democrats would need a net gain of seven seats. As many as three dozen of the 435 contests are considered close.
