I doubt old Mitt is that stupid. The ads of how he ravaged the middle class and companies and all those workers are still fresh in the minds of voters. And having a long term employee on TV describing how Mittens took their company, killed their jobs, all for fast profit, doesn't play well with the voters. That hasn't changed. And if anyone knows how to focus an attack campaign on that little Romney venture, it would be the Clinton's. Oh the horror.
CEOs of venture firms dont have to know what everyone wants and there is a lot less uncertainty involved than what, say, Richard Branson, Jen Hsuang, or Thomas J Kalinske have worked with. Romney would just change the name and everyone would still know what it was. He cant fool the same person more than once just like I cant and that is because we are not observant.
Also, Romney's not a good communicator and his gaffes are accidental. He often has the wrong info (like I do), isnt good at connecting the dots (similar to me), has an inability to quickly and accurately fill in the blanks (same with me) while there is reason to believe that gaffes from Bush (43 at least), both Clintons, Biden, and Obama are on purpose.
Remember, the RNC spent a lot of time training Romney for the debates. He stutters a lot and gets stunned easily just like I do (although Romney isnt quite as bad as I am when it comes to verbal fluidity). The RNConvention '12 was super-scripted and Reince Priebus et al. drew up a shitload of rules and threatened the fuck out of people because Romney cant handle disorder just like i cant. The RNConvention of McFailin'08 was nowhere near as scripted and that is because McCain's IQ was tested to be ~133.
And his cephalic index is definitely below 80 so you know he's not smart enough to succeed on his own.
