John Mccain not fit to be president?

I am sick and tired of people saying that being a war hero doesnt make you a president. Say that to george washington or dwight eisenhower. Yes, there have been some that have been a dissapointment like grant, but serving your country no matter what the cost, is a big et, bc it gives candidates the confidence that you will country before anything else. So if a war hero is not a good credential than what is. Being very articulate like richard nixon? Or to look presidential like john f kennedy or bill clinton? Or to have great ideas for the country like andrew jackson? all of these qualities are destructive, and i dont think stance on issues should be a consideration for president, than anyone from the electorate can be president, but you have accomplished, like not only prepared to give up your life for a country but to be tortured for a country for five years. Another thing is if you think age is a factor, than say that to england who elected churchill at 77 and to vajpayee ofindia
