ICHEOKU says yes, Senator John McCain is a perpetually angry person, unforgiving and it once again showed. He did not act out of any deep rooted concerns or convictions about the bill as every possible tweaking of the Healthcare repeal that was possible was made to accommodate needed concerns; such that it become merely a shadow of its original self and now termed a "skinny" repeal, yet McCain did not bulge. He acted with a malicious mind in order to spite the president whose main agenda is a Healthcare reform, which drove his campaign message. Yes, John McCain acted to get back at the president and take his own pound of flesh from the president, for his remark that "those who were not captured" are the type of heroes he likes. It is obvious that Senator John McCain has not forgiven the president for the remark which the then candidate Trump made concerning the Senator's years of being detained inside a Hanoi prison. The Senator, known for his unforgiving spirit, clearly understood then that Trump's jab was meant to diminish his hero status and he has never forgiven Trump ever since. So when a golden opportunity presented itself to get back at Trump, the Senator did not show magnanimity but cashed in, measure for measure.
Senator John McCain is as mercurial as he is a maverick, admitted he denied being a maverick when called out on that his special streak of his. ICHEOKU says here is a man who then as presidential candidate campaigned on repealing Obamacare and now that the opportunity finally arrived to get it done, he shirked and shied away; simply because he had an ax to grind with the president. Such an unforgiving spirit is not good for anyone, especially a senator of the United States of America who is now making his personal feeling come before the interest of the people of Arizona as well as the general United States of America citizens. Sad!
ICHEOKU says Senator John McCain is simply lashing out, probably because his days are numbered and he does not care about burning down the house as he departs. That the president sent him good wishes while in the hospital and even called him an American hero was not enough for the Senator to forgive a past squabble. Those paying attention and who are versatile with body language, saw the telltale signs of McCain going rogue with the repeal when he went off against talk radio hosts, calling them names and urging politicians to ignore them. It was unlike McCain and he was once a fan; but apparently he no longer have any use or need for them due to changing life circumstances and he told them to take hike. Otherwise how else could any Republican argue against talk radio hosts who literally direct conservative public opinions in the country; except to say that having crossed the bridge and have no further need for them, he is now telling the bridge and its builders to go to hell.
Senator John McCain also probably voted against the repeal just out of jealousy and envy of a president who achieved and accomplished more than he dreamt of by winning the United States presidency on a first try. The senator lost to then Barack Obama in 2008 after years in politics and here came Donald John Trump, on a first attempt, securing victory and is now the President of the United States of America. John McCain is human and humans do get envious and jealous of what they don't and couldn't have. So when all these considerations are factored in, the true picture comes to live and one can begin to actually truly understand what it is that moves McCain and indeed moved him to vote against the repeal effort - he is petty and little.
Possibly too, because of his latest diagnosis of incurable brain cancer, he decided to make one last final stand, a last major act, before passing on. He wanted to leave one lasting legacy for which he will be remembered among other things, by voting against the repeal. Although one of three Republicans to vote against it, but his was the consequential vote in the 49 - 51 downer. The Senator has since returned to his Arizona hospital to begin a regimen of treatment which will only ease him out, as their is no cure for glioblastoma, the same malignant brain cancer which killed Massachusetts Senator Ted Kennedy. But why the senator want such epitaph is really beyond many people's understanding; except that he is John McCain and he is irascible and choleric and it once again showed.
