Secondly, I would challenge greatly that Obama fully understands what's going on. He is clueless on the economy, clueless on foreign affairs, and clueless on the art of the possible in politics. The man has such an over inflated opinion of himself that he is incapable of listening to those who might actually know something that could help him govern.
Thirdly, not only does he lack executive experience, he more importantly lacks executive expertise. It's like turning over a company you worked to create and build all you life to your spoiled only child - he's entitled, but he hasn't the foggiest idea how to actually run the place and in no time it falls off a cliff. You might have had more success electing one of the Kardashians - equally as high profile, yet experienced in running a successful business and making things happen. And to think, the man is in his early 50s and your country is going to be paying through the nose the better part of another 50 years to keep him safe and cater to him because he's sure to demand his perks.
Finally, most importantly by competence, I meant he's not a leader. He moves no one to his goals or policy positions. On the foreign relations files, can anyone name even one success the man has lead from start to finish with accomplishment? At home, what domestic policy successes does he have? You can say Obamacare, but in truth that is the brainchild of the Democrat Congress, with precious little help or leadership from Obama but he rushed in at the end when the deal was done to claim ownership.
You just have to look at the two main issues that arose at the start of his second term - gun control and immigration reform - there was a push in the country, a grassroots push, to perhaps do something significant about access to guns and the types of guns and ammunition available, however, Obama's involvement cratered the support because he doesn't know how to work a compromise, to lead by the power of his convictions, to convince people of the rightness of his goals. Likewise, with immigration reform - the Senate was working behind the scenes on a reform package and having bipartisan success and were about to announce their outline of a plan and Obama, ever the roadblock, had to have a White House announcement on the subject the day before the Senate announcement, and that set the process back months and likely killed it.
The man holds the highest office in America, and for that matter the world, and that office is to be respected. But the man holding that position is a disgrace to that office, in my view, and it does no good to brush off his failures - they are serious and they have set back your country's recovery and prosperity by many years if not decades.
