There are 113 seats in Rhode Island’s General Assembly, and more than half of those House and Senate seats are being contested this year – just not necessarily in November.

That’s because there are 18 state legislative districts with a primary contest but no general-election race. These are all places where more than one Democrat filed to run in the primary, but no Republican or third-party candidate filed to run against the winning Dem in November.

Put another way, voters in these 18 districts have a choice on Sept. 11 but not on Nov. 6; barring a highly improbable victorious write-in campaign, the winner of tomorrow’s primary will be these districts’ next lawmaker.

Between the 18 primary-only districts and the 30 districts with no competition at all, nearly half of the General Assembly’s membership for the 2013-14 term will be known on Wednesday morning – 48 of 113 seats.

After the jump, a look at which districts have contested primary elections but uncontested general elections. Incumbents are in bold. If the current lawmaker isn’t in the primary, I put the name in brackets.
