Boswell will face off against Rep. Tom Latham (R-Iowa), whose district was eliminated by redistricting. Boswell has represented most of the territory before, but the district leans slightly Republican — Obama would have won it by five points, but President George W. Bush would have carried it by six.
The group, technically the "policy" side of the Crossroads operation, is spending almost $80,000 on the ad, bringing its total spending in the district to a whopping $370,000 since late October. By comparison, that's just more than half the amount Boswell's 2010 opponent spent in his entire campaign.
