Congressional Quarterly  is changing its forecasts on two competitive U.S. House races in Nevada, and in both cases, there is good news for the Democrats.

CQ announced Wednesday it was shifting the 2nd Congressional District race between U.S. Rep. Dean Heller (R-Carson City) and Democrat Jill Derby from "Republican" to "Leans Republican," acknowledging the race is closer than previously thought.

The forecast looks even better for state Sen. Dina Titus (D-Henderson) in the 3rd Congressional District, the publication said. CQ switched Titus' race with incumbent U.S. Rep. Jon Porter (R-Henderson) from "Leans Republican" to its most competitive category: "No clear favorite."

The publication cited voter registration numbers that now favor Democrats, as well as investments from the national Democratic machinery in the two races as signs that things are looking up for Titus and Derby.

An analysis published with the projections did note that the two incumbents hold fundraising advantages over their Democratic challengers.
