Obama saved GM, not the entire industry. Instead of a normal structured bankruptcy he pushed through a bankruptcy that caused GM's creditors to lose billions and yet GM still lost 25% of it's workforce. The gov't still owns GM stock and won't sell them as the full extent of gov't expenditure would then be known. And the underlying cause of near GM collapse hasn't been fixed, which was very high pay, gold plated benefits, that make the company vulnerable to serious economic downturns. Trump on the other hand is looking to create an environment where companies can thrive and provide jobs to everyone willing to work and reducing incentives not to work.
