And oft-discussed theme of the -bats is that John McCain has had cancer like, four times. Plus, he's old.
1. My father was diagnosed with Non-Hodgkins Lymphoma in 1976. Life expectancy: 6 months. He died in 2000.
2. Ageism: McCain is 72. Last I checked, there's no age limit imposed on the office he seeks. Also, bringing up age puts you on the opposite side of a HUGE majority of voters, the retired/elderly.
3. If he can survive years of abuse and torture in a Vietnamese shithole, I'd imagine having a team of doctors and nurses at his house who are tasked with keeping him healthy will likely keep him away from the light at the end of the tunnel.
4. Given his choice of VP, his passing isn't a bug, it's a feature.
