So you want to be a seismologist

In this case, the obvious parsing is: "(Sometimes I wonder if) People like Jeanine Gorafalo or Rachel Maddow are communists, but cannot say so because doing so would jeopardize their reputation and ultimately their careers."

Not to get semantic, this being the Lounge and all...

I would parse it;

• Sometimes - pretty disposable...
  
• I wonder if people like Jeanine Gorafalo or Rachel Maddow are communists,
  
• but [I] cannot say so...
  
• because doing so would jeopardize their reputation and ultimately their careers."

Since it was "I" who wondered in the first part, it would follow that it would be "I" who cannot say in the second part. It's vague at best if it's [I] or [they].

I'm glad to see though that some people can read BS. You will alert me though if he does form an original thought? I can't make much sense of his gibberish.
