[Ed. – Would that be a classic case of “necessarily skyrocketing”?]
Arizona Sen. John McCain’s favorable rating is 58% after he cast the vote that sank GOP attempts to repeal the Affordable Care Act. That is five points higher than McCain’s previous reading from August 2015, with a surge in Democratic favorability more than making up for a decline among McCain’s fellow Republicans.
The results are based on an Aug. 2-6 Gallup poll, conducted shortly after McCain returned to the Senate from his home in Arizona after having emergency surgery and finding out he had an aggressive form of brain cancer. …
Democrats now view McCain much more positively than they did two years ago, with their 71% favorable ratings representing a 22-percentage-point increase since then. Republicans’ opinions have grown more negative, though their 10-point decline (from 61% to 51%) is about half as large as the Democratic increase. Independents’ opinions of McCain are virtually the same as they were two years ago.
