The closest we’re likely to get to the former president speaking out anytime soon? Laura Bush on Cheney and the GOP:

“I think that’s [Cheney’s] right as a citizen of the U.S., and I think he also feels obligated, and so I understand why he wants to speak out,” Laura Bush said in an interview on ABC’s Good Morning America broadcast Monday.
“On the other hand, George feels like as a former president that he owes President Obama his silence on issues, and that there’s no reason to second guess any decisions that he makes.” …
The former first lady said that she and her husband have discussed the civil war over the Republican Party’s future, but downplayed the intra-party conflict.
“It’s like creative tension within a party for people to talk about…how they want to be represented,” she said.
