(CNN) - Mitt Romney sent a note Saturday to his campaign backers saying he and his wife "cannot thank you enough for supporting and believing in our cause."
"This was more than just a campaign -- this was a national movement," he said. "Thank you for the work that you did -- going across neighborhoods to knock on doors and put up yard signs. Thanks for making phone calls, coming to rallies, donating funds, and convincing friends and family to join our team."
He did not specifically address his loss or President Obama in the message.
"We still believe that better days are ahead. It's up to us to rally together to renew America's promise and restore American greatness," the message said.
The message did not address Romney's future plans. He has told supporters that one immediate emphasis is to help find jobs for the 400 campaign staffers.
"From the bottom of our hearts, Ann and I thank you for your support, prayers, efforts, and vote. We are forever grateful to each and every one of you. Today's a new day. Keep believing in America," Romney wrote before ending it saying, "Thank You."
