Staggered Senate
Senators serve four-year terms, with one two-year term after each redistricting, so about half the seats are on the ballot each election.
11 of 21 seats on the ballot; 10 holdovers (7 D, 3 R) serve until a later election.

The Delaware environment
The environment Delaware's governor, statewide and legislative races run in, read from their polls against what the fundamentals expect. Its federal races run in the national environment.

The polled state races behind it
No governor, statewide or legislative race in Delaware is polled yet, so its state races run at the national environment.
Over time
Each polled race's average, minus what the fundamentals expect at the national environment, in national-environment points (a dot right of center runs more Democratic than expected). Readings are weighted by poll precision and office (governor most, then other statewide races, the Senate, legislative and House races), centered on the national average and pulled toward zero, so a thinly polled state stays near the nation. Governor, statewide and legislative races use the Delaware environment in full; Senate and House races 0% of it. Each race's own polls are left out of the environment it uses.
