Republicans have more seats in the highly vulnerable category than they had at this point in 2006

Why is this so potentially ominous for the GOP? Because in both 2006 and 2010, the party that controlled Congress wound up losing significantly more seats than the August highly vulnerable ratings would suggest.
Whats more, Walter says that Republicans already have more seats in the highly vulnerable category than they had at this point in 2006 or than Democrats had in August of 2010.
In the end, Walter concludes that the GOP had better pray something big changes between now and November, or else they face the very real prospect of an electoral wipeout.
If 2018 follows a similar pattern to 2006 and 2010 where less vulnerable seats move into more vulnerable territory in the fall the GOP is almost certain to lose their majority, she writes.
