I heard about this today on the radio, but I didn't realize his tumor was this bad. Terrible news.
And the tragic irony here is that his mother (who's around 105, if I recall correctly) is very likely to see her son die, which is always one of the worst things a mother can experience.
The terrible irony attached to this is amazing and appalling, because the exact same thing happened to Joe Biden in 2015, and this is the exact same cancer that killed Beau, down to type and staging.
I'm actually stunned speechless. It was actually going to be a plot point in my Giffords timeline that McCain would be struck down by cancer, and good god almighty, I never thought, nor wanted to imagine, that I would actually be
right. I absolutely hate McCain as a politician, but I would wish end-stage brain cancer on literally nobody. I sincerely hope McCain beats the tremendously long odds attached to GBM, but if not, I'm glad he at least got to have 81 years.
