There is actually a lot less risk of democrat crossover than usual. A heavily contested Democrat race for governor (polls show a chance for a runoff between the Mexican lesbian and the White man); a lot of empty congressional seats on the table, even a lightly contested race for senate on the Democrat side all suggest that the Dems will stay on their side of the booth this year.
The big threat, as always, is the Country Club/CoC crowd.
That is encouraging. However, and I hope my concerns are overblown, they do have teachers and public school types worked up.
