Senator John McCain may not be a Martian. But he is a giant – the Giant of the Senate.
Or so reports Reuters: Sarah Binder, a scholar at the Brookings Institution, is reported as saying that McCain’s colleagues perceive him as a ‘giant’ of the Senate. 
The Giant of the Senate is not feeling so well these days. McCain has been diagnosed with an aggressive form of brain cancer. Already they are inscribing “Giant of the Senate” on his tombstone, as they had previously done with Senator Ted Kennedy, “The Lion of the Senate.”
When they secretly decide that you are history, they break out the chisel and begin inscribing your tombstone.
On the other hand, in 2015 former president Jimmy Carter announced that melanoma had been found in his brain. Yet later that same year medical scans no longer showed any cancer.  So maybe John McCain will have a similar occurrence.
In the short video hopefully viewable at the top, you can see McCain in Ukraine. He was there in December 2013. Standing with McCain was the leader Of Ukraine’s ultra-Nationalist Svoboda Party, Oleh Tyahnybok. The “optics” were bad on this one: Did someone forget to tell the Giant of the Senate that the Svoboda Party is neo-Nazi?
After the stunning election of Donald Trump, The Washington Post reported that McCain “is serving as a shadow secretary of state, trying to clean up or refute statements and positions that [President] Trump has made.”  (Many have alleged that former-president Barack Obama has established a “shadow government” in Washington, DC at his newly acquired mansion.) Now Reuters also suggests the Giant has been working as a shadow secretary of state. “McCain has traveled the globe on trips some analysts say are efforts to soothe the concerns of U.S. allies…”  With shadow secretary McCain no longer undermining the efforts of the legitimate secretary of state, Rex Tillerson, this already reduces the odds of war with Russia. Who will the new “shadow secretary” be?
