Article in Forbes from August shows stakes in (or being looked at),up to 30 companies by the Government. None of those interests are controlling.
Most conservatives are against the Government owning stakes in companies, especially a controlling stake. However, actually owning a piece of a company, and having a vested interest with making the company survive and prosper, (if that is possible for a Government endeavor), is much better than just handing them truckloads of cash and hoping for the best (remember Solyndra?).
