Several sites and individuals publish predictions of competitive seats. These predictions looked at factors such as the strength of the
incumbent (if the incumbent is running for re-election), the strength of the candidates, and the partisan leanings of the state (reflected in part by the state's
Cook Partisan Voting Index rating). The predictions assigned ratings to each seat, with the rating indicating a party's predicted advantage in winning that seat. Most election predictors use: • "tossup": no advantage • "tilt" (used by some predictors): advantage that is not quite as strong as "lean" • "lean": slight advantage • "likely": significant, but surmountable, advantage • "safe" or "solid": near-certain chance of victory " after the incumbent's name.
