Connecticut Senate candidate Richard Blumenthal apologizes via e-mail, Sen. Michael Bennet (D-Colo.) survives his convention in Colorado, and Hawaii still looks problematic for Democrats.

Too late to apologize?

Earlier this week, Blumenthal said he regretted that he "misspoke" and took "full responsibility" for mischaracterizing his service during the Vietnam War. But he didn't apologize — until Sunday. After getting criticized for not saying sorry to veterans, Blumenthal's camp issued a statement to the Hartford Courant on Sunday.

"I have made mistakes and I am sorry. I truly regret offending anyone,'' Blumenthal said. "I will always champion the cause of Connecticut's and our nation's veterans."

The thriller in Broomfield

Senate candidate Andrew Romanoff (D) captured 60.4 percent of the vote at the Colorado Democratic Party's state convention Saturday, but failed to keep Bennet off the August primary ballot. The incumbent got support from 39.6 percent of the delegates — he needed only 30 percent to keep his place.

Bennet said he was "thrilled" by the result, but he wasn’t taking any chances. His campaign had organized an effort to petition his way onto the ballot, should he fail at the party convention.

See you in September

Democrats have been talking down the GOP's win in the Hawaii special House election on Saturday as an anomaly because, the party says, they'll easily recapture the seat in November. But the same dynamics that cost them the race this time — a party divided by two candidates — could still exist.

Former Rep. Ed Case (D) sent supporters an e-mail Monday saying, "tomorrow is a new day, the start of our next chapters together, and I'm excited to begin anew."

As Representative-elect Charles Djou (R) explained recently, "Colleen [Hanabusa] and Ed both dislike me, but they hate each other."
