Democrats will hold a slim majority in the next Iowa Senate: most likely 26-24 or 27-23, depending on the outcome of one recount and one special election in December. But the experience gap between the two parties' caucuses is wider than I've ever seen, and perhaps unprecedented.
Only five Republicans who will serve in the next Iowa Senate have more than four years experience in the legislature's upper chamber. Most of the old hands aren't on the GOP leadership team. By comparison, eighteen Senate Democrats have held that office for more than four years. Thirteen of those have served in the upper chamber for at least a decade.
Many newcomers to the Iowa Senate have helped oversee public-sector budgets and programs as county supervisors, mayors, or members of city councils and school boards. Nevertheless, new legislators have a steep learning curve because state government is more complex than local government, and Iowa House and Senate members consider a wider range of issues during a typical legislative session. Whereas eleven Senate Democrats previously served in the Iowa House, only three sitting Republicans came to the Senate with that background. If the GOP had gained control of the upper chamber in this year's elections, they would have been forced to put quite a few rookies in charge of standing committees.
After the jump I've posted details on the tenure of all incoming Iowa Senate members, indicating members of each party's leadership team and past service in the Iowa House.
