Here's an idea I can heartily endorse: Bush and Cheney resign now. That would put House Speaker Nancy Pelosi in charge -- and beginning an early implementation of the Obama regime. There's an Arkie-related precedent for the idea.
In the past, presidents have not taken well to suggestions that they hand over the reins before the last possible minute. Senator J. William Fulbright suggested a plan along those lines when Harry Truman was coming to the end of a term in a state of deep unpopularity, and Truman called him “Halfbright” for the rest of his life. Bush might not love the idea of quitting before he has a chance to light the Christmas tree or commute the execution of one last presidential turkey. After all, he still has a couple more trips planned. And last-minute regulations to issue. (So many national parks to despoil, so many endangered species to exterminate ... .) And then there’s all the packing.
On the other hand, he might want to consider his legacy, such as it is.
