I just finished watching this news video about the breaking news and it doesn't sound good at all. Here's a link to that video:

Sen. McCain is likely to go through radiation and chemo through his recovery process. The doctors and family are making it sound like he's all good, but I'm not so sure.
It sounds like they are trying to protect his seat in the Senate as I'm sure once this news settles in that there will be some calls for the Senator to resign and allow someone else to take over his seat in the Senate.
Let's just look at the facts here. We have an 80 year old man with brain cancer that will likely have to go through some of the worst treatments known (radiation/chemo). This isn't something you just bounce back from and you're good to go back to work next week.
This could provide a very interesting situation. Kelli Ward, who lost to Sen McCain in the Republican Primaries last year, would be an assumed front runner in the event of a special election. She is currently running in the 2018 elections against Jeff Flake, but I'm sure she'd change that if Sen McCain couldn't keep his seat.
It'll be interesting to see how all this plays out!
