He, somehow, managed to have the federal government bail out his enterprises on multiple occasions.
1) The Salt Lake City Olympics was rescued by the US taxpayer - http://www.mediaite....ic-welfare-queen/ - not by some magic managment skills on his part.
2) Romney supposedly screwed over the FDIC to save Bain in 1990s and made millions in the process - http://www.rollingst...t-romney-20120829
Few expect Romney to be up on the ins-and-outs of running a big IT project, but this Orca episode is yet another illustration of his incompetence in running a campaign. And his campaign seems to fit with the reality of his professional career - his "I'm the CEO so pay fealty to me" attitude and unwillingness to accept criticism (recall his attitude about being questioned during the "corporations are people my friend" episode), his history of bullying in school, his "service" in Paris during Vietnam, his kids "service" in working on his campaign, etc., etc.
I think he lost because a majority of people didn't like his policy proposals and his associations with reactionaries in Congress, his lies, his refusal to have press conferences, his refusal to release his tax returns, and so forth, but his incompetence in running his campaign didn't help.
