But Cornyn suggested that without Rep. Mike Castle (R-Del.) as the Republican nominee, the seat is less winnable for his party this fall.


"It's no secret that I believe Castle would have won that race handily," Cornyn said. 

On Wednesday, Castle decided against waging a write-in bid this fall, an option he told reporters last week that he was considering. The latest polling in the race gives Coons a double-digit lead over O'Donnell.
