John McCain is a complicated figure. No one can deny his heroism and that he stuck to his beliefs. Unfortunately, none of this will be his lasting legacy. His real impact on American politics is that he legitimized crazy when selecting the completely unqualified VP candidate of Sarah Palin. This was the start of insane right-wing politics being see as legitimate. An established republican selected a complete loonie for his VP pick just to try and gain votes from the extreme side of his party, the religious nuts. A desperate and terrible move for the country. This may not have been the catalyst for Trumpisum but it certainly opened the gates to crazytown. I don’t believe we would have a wackjob like Trump as president if McCain didn’t select Palin.
