No, what has added 10 trillion in debt is largely inflation and interest. If you actually paid attention to what Obama's done, he's not done as bad as you think. He's created almost 9 million more jobs (+8,649 thousand), for instance.

The one thing that Obama IS guilty of, however, is making the rich even richer and the poor even poorer, as a result of giving subpar improvement in wages to lower and middle class. But Trump supporters don't generally criticize him for this, because they're often themselves under the impression that the richest deserve their money and that the poorest are lazy.
Maybe you should pay less attention to popular media, and more attention to actual economics. Just because people repeat the same nonsense over and over ad infinitum, doesn't make it true.
Another thing you seem to forget, is the fact that a President's actions doesn't usually come fully into effect until his second term or even after his terms are over. Much of the 10 trillion dollar increase in debt under Obama (that isn't due to inflation and interest) is the repercussions of President Bush's policies.
But such is the fate of every President - to get blamed for everything that his predecessor did because people have a hard time thinking beyond a few years timeframe. And yes, Obama has indeed "failed" to fix a lot of Bush's blunders, but maybe you should blame Bush for causing them to begin with, and not blame the one's who fail to fix it.
Just saying. Anyone, I'm no expert either, so let's give it a rest. I'm sure you got some valid point, even if I don't see them right now.
Peace.
