Rep. Kevin Kiley (CA-3) has quit the republican party and registered as the only independent in the US House. Kiley's district was recently redrawn. He is currently running running for the newly drawn CA-6 as an independent this November. His defection technically changes the partisan balance of the House to 217-GOP, 214-DEM, 1-I though from a practical standpoint it doesn't impact much since Kiley will continue to caucus with the GOP.
