It's not seismic but it's moving!

It's beginning to look like 2010. It's extremely hard to keep track of 435 House races but Stuart Rothenberg does just that. What Rothenberg and his writer Nathan Gonzales are seeing is a subtle shift in competitive House races. In a Roll Call post Gonzales writes;

Democrats believe, as competitive races become more engaged and the party exercises some of its financial advantage to get its message out, that some contests will turn in their favor. That scenario is possible, but in many cases Democratic challenges aren’t developing as quickly as expected and some Democratic incumbents are struggling to gain their footing.
We’re changing The Rothenberg Political Report/Roll Call ratings in a half dozen House races, all in favor of Republican candidates:
California’s 21st District: The race between Republican Rep. David Valadao and Democrat Amanda Renteria moves from Tossup/Tilts Republican to Leans Republican.
California’s 26th District: The race between Democratic Rep. Julia Brownley and Republican Jeff Gorell moves from Democrat Favored to Leans Democratic.
Illinois’s 12th District: The race between Democratic Rep. Bill Enyart and Republican Mike Bost moves from Leans Democratic to Tossup/Tilts Democratic.
Illinois’s 13th District: The race between Republican Rep. Rodney Davis and Democrat Ann Callis moves from Tossup/Tilts Republican to Leans Republican.
Michigan’s 8th District: The race between Republican Mike Bishop and Democrat Eric Schertzing moves from Leans Republican to Republican Favored.
Texas’s 23rd District: The race between Democratic Rep. Pete Gallego and Republican Will Hurd moves from Democrat Favored to Leans Democrat.

A race that I find interesting is the New Jersey Senate race. While trendy and publicly affable Cory Booker has a 7 point lead in the most recent poll his lead is quickly sinking in the race against Jeff Bell. At 70 Bell is running in his first statewide race. The economist/author started the race with a pronounced disadvantage in name recognition and resources but seems capable of turning the race competitive.
