You listed the important, tough questions Lauer did not, but should have asked, and he gave Davis plenty of time to spin out his pre-packaged answers, which were echoed by his wife. It wasn't candid at all, there no surprises for Davis, but it was funny when Lauer practically LOL at how victimized Davis & wife portrayed themselves by the evil Republicans.
I think Lauer's questions about the Clintons coming in to rescue Davis were important. If Davis squeaks outta this mess, you better believe Hillary and Bill will claim it was because of them. Davis seemed reluctant to even admit they were coming.
