The Northwest Boise/Garden City district is now represented by three Democrats, but it has elected Republicans in recent years and an open House seat has the GOP eyeing a pickup.
The 7 p.m. forum is sponsored by the West Bench Neighborhood Association and will be held at the library at Ustick and Cole roads.
On the ballot for the Senate are incumbent Democrat Les Bock vs. GOP nominee Joan Cloonan.
In the open House seat, Democrat Hy Kloc faces Republican Graham Paterson.
In the second House seat, incumbent Democrat Grant Burgoyne faces Republican Lee-Mark Ruff and Libertarian Jeffrey Laing.
