WILMINGTON, Del. – Democratic Senate candidate Chris CoonsChris Andrew CoonsSenate Democrats leery of nixing filibuster Security concerns mount ahead of Biden inauguration Trump impeachment collides with Biden's agenda MORE brushed aside suggestions Wednesday that Christine O’Donnell’s win in the Republican primary gives him an easy race this fall.

“We don't take anything for granted,” he told reporters at Libby’s restaurant in downtown Wilmington, where Coons met with diners for some retail politicking.

O’Donnell shocked Rep. Mike Castle (R-Del.) Tuesday night, defeating the longtime lawmaker in a contentious Republican primary.

Most Republican strategists view O’Donnell as the weaker general election opponent against Coons and see the party’s path to a Senate majority as severely damaged by her victory. The Cook Political Report shifted its projection from the race to likely Democrat from likely Republican after O'Donnell's win.

Asked whether he agreed with the characterization that O’Donnell was too extreme for the state, Coons demurred Wednesday.

“That's what the election is for on November 2,” said Coons, who did acknowledge the general election will be “a different sort of race” than the one he was expecting.

Coons avoided any direct attacks on O’Donnell, but did characterize her as someone who “doesn't represent the sorts of values” Delaware voters are looking for.

Coons said he was surprised by how nasty the Republican primary was, and that it did not reflect the sort of campaign he wanted to run.

“I don't think voters respond well to personal attacks and there was a lot of them from both campaigns,” said Coons. “If there are baseless personal attacks against me of the sort that we saw in the Republican primary, I'll respond to them. But I’m not the sort of person who wants to get into that.”

Coons also said he phoned Castle Tuesday night to “thank him for his years of service,” calling the longtime congressman a “good, decent and responsible public servant.”

Coons said he has not phoned O’Donnell but said he looks forward to greeting her at a candidate forum scheduled for Thursday night.

Coons also challenged O’Donnell to a series of debates up and down the state.
