The Iowa Independent offers up this look at the money race for the state Senate. Things look pretty darn positive:

Democrats already have a 30-to-20 advantage, and in five battleground districts identified earlier this year by The Iowa Independent, Democratic candidates have an overwhelming advantage in cash on hand, with $224,732 compared to $20,071 for the Republicans. Two of those five seats are currently held by retiring Republicans, meaning the Democrats are in good position to expand their majority in the Senate.

Republicans in the state seem to recognize that challenging upper chamber races will demand an uphill battle and are instead focusing on the House.
