Analysis
Smart Politics analyzed in early October how Democrats were bracing for a bloodbath in elections for the Iowa House of Representatives.

Democrats are at a disadvantage of maintaining control of the lower chamber on almost every dimension – even putting aside the Republican momentum that is brewing in the Hawkeye State.

Most glaringly, Democrats set a record in 2010 for the largest number of districts in which a major political party has failed to field a House candidate since the lower chamber became a 100-seat body 40 years ago (25).

Meanwhile, Republicans fielded candidates in 92 races – their best showing in 30 years.

Democrats are also having to defend 10 open seats, compared to just six for the Republicans.

All of this adds up to a big day for Republicans, with the real potential of double-digit gains in the House like they enjoyed during the Republican Revolution of 1994.

Projection
Partisan shift: GOP +10
Partisan control: GOP takes control
