This week is going to be a very bad week for McCain (unless there's something I don't know):
* The press is reversing on ACORN. My guess is that this is the result of the Obama camp requesting that the special investigator who is looking into the attorney firings also look into the FBI's investigation of ACORN. I don't expect a full reversal, but I do think that CNN, among others, will back down from their condemnation of ACORN and point out that registration fraud is a very different thing from voter fraud, and that it's not a centrally-controlled thing.
* Colin Powell endorsed Obama, yesterday, and one imagines this will bring another wave of defections from moderate-right pundits against the McCain camp. The endorsement included Powell's condemnation of the press for letting "Muslim" become a slur and his condemnation of the press and the McCain camp for harping on Ayers. This will dominate the news this week.
* David Letterman seems to have almost pushed the G. Gordon Liddy/McCain friendship out into the open. It was well-known on blogs for weeks, but it hasn't yet made its way to the mainstream press. My guess is that it gets mentioned once or twice this week, but that the press doesn't pull out the stops. This is a man who has plotted multiple assassinations and kidnappings (this is only what we know he did) and has said as recently as 1990 that, if his listeners ever want to shoot an ATF agent, to aim for the head.
* Obama raised $150 Million this month. This will also dominate the news this week.
* The issue of health records is also coming back into the spotlight. The New York Times has a five page story on why candidates should release their health records. This may be ostensibly aimed at all the candidates, but McCain clearly has the most to lose.
