In a CNN interview on Thursday, anchor Chris Cuomo asked Hillary Clinton if presumptive Republican presidential nominee Donald Trump is qualified to be President of the United States. Her answer was simple and to the point:  No, I do not. Question: "Do you think Donald Trump is qualified to be president?""No, I do not."  Hillaryhttps://t.co/04viDc5G7t  Hillary Clinton (@HillaryClinton) May 19, 2016Clinton then elaborated on her direct answer, and laid out the case she will probably continue to make between now and Election Day.She called the crash of an EgyptAir flight early Thursday an act of terrorism and went on to portray Mr. Trump as dangerously out of step with what a commander in chief would need to do to combat such attacks.She cited his proposal to temporarily bar Muslims from entering American borders, his comments about diminishing the United States  involvement in NATO and his remarks that he would negotiate directly with the North Korean dictator, Kim Jong-un, as evidence of how  unmoored  Mr. Trump is on foreign policy.The Clinton campaign has been hammering at Trump s radical ideas and temperament to make the case to voters that he is far too unstable to be given access to America s military and nuclear arsenal. At the same time, members of the intelligence community have already expressed concerns that Trump will even be allowed to receive classified briefings as the party nominees are traditionally given.That message will also likely be amplified in the multi-million dollar advertising and voter mobilization campaign that began this week from the super PAC Priorities USA.The attacks on Trump actually echo some of the attacks made by Democrats in 1964 against Republican presidential candidate Barry Goldwater, who is consider the godfather of modern right-wing conservatism. President Lyndon Johnson s ad,  Daisy, speculated that nuclear Armageddon could come if Goldwater was elected president.The ad was so effective, it only ran once. That fall, Johnson defeated Goldwater in an epic landslide, 61% to 38%.Featured image via Twitter
