Please.
Fred was treated successfully for this three years ago.
Let's not spin the politics of this, since we have no idea what the impact is on Fred's decision to enter the race. Let's hope he stays healthy, whether or not he enters the race.
Rudy = cancer survivor
McCain = cancer survivor
If anything, three high profile cancer survivors, along with Liz Edwards, will bring cancer treatment, etc. into the national spotlight after being sidelined by things like AIDS, Bird Flu, etc.
Unfortunately and perhaps unfairly, as a potential political candidate, the medical complexity of "lymphoma" translates for too many voters into uncertainty, and that is not a good thing for a candidate. Both Rudy and McCain have had significant cancers in the past, but they can plausibly claim to be cured whereas Fred can only claim to be "in remission" and to have a good prognosis. Even if that is true and he's backed up by a bunch of doctors there will be doubters. If any of the three are nominated the MSM will keep their health in the news - in contrast to Hillary. whose health records will stay filed with Bill's. In Fred's case the MSM can take things a step further. They can say nice things about him and compare him to Paul Tsongas. IIRC discussion of Tsongas's remitted lymphoma wasn't helping him in the polls prior to its sad relapse. Adding this to a late start and a large initial money gap behind those already in leaves potential candidate Fred with a large hill to climb. However I don't think this would hurt him as a VP candidate.
Some have interpreted Fred releasing this as advance spin control preceding a campaign launch. That is plausible. However it also is plausible that he heard the story was going to be leaked, either by somebody in the MSM or by some other candidate, and wanted to control the story for the sake of his own reputation. There are too many unsavory reporters, and politicians, in both parties, to rule out the latter possibility completely.
