What the protesters want is for Mitt Romney to intervene on their behalf, leveraging both his national profile and his relationship with Bain Capital executives. And, in theory, it makes sense. After all, what presidential candidate wouldn’t want to help save 170 American manufacturing jobs? Particularly someone who talks about getting tough with China?

But it simply isn’t going to happen.

For the uninitiated, here’s a quick backgrounder: Late last year, a Bain-owned company called Sensata Technologies (ST) agreed to buy an auto-sensor manufacturing unit from Honeywell (HON). From the outset, Sensata said that it planned to move the jobs overseas at year-end 2012, since the majority of its auto-sensor business is in Asia. In fact, Sensdata didn’t even buy the manufacturing facility from Honeywell. It leased it, with Honeywell expected to hang a for-sale sign when Sensata moves out in a few months.

To be sure, this is a horrible situation for the Sensata employees – the vast majority of whom have not yet found other employment (Honeywell hired just a small number of folks to work in its other Freeport facilities). After all, Sensata has never suggested that the plant was unprofitable. It simply thinks the effort would be more profitable elsewhere.

Unfortunately, the workers are barking up the wrong tree with Romney.

Remember, this is the guy whose campaign got into a well-publicized scuffle over whether he really stopped making decisions for Bain Capital in 1999 or 2002 (for the record, it was 1999). How could he possibly open himself up to legitimate charges of influencing Bain’s behavior in 2012? Even if one argues it’s the right thing to do for the workers, it’s not the politically feasible thing to do (and, if anything, Romney tries to be a pragmatist in such matters).

Moreover, there is little guarantee that a Romney plea would even save the jobs. Yes, he has friends and former colleagues on the Sensata board, including chairman Paul Edgerley. But they have fiduciary responsibilities to their own investors, and Sensata has made it clear that the best financial move is to shutter Freeport. In addition, Bain could have future fundraising trouble if Romney is elected president. After all, who wants to invest in a private equity firm that seems to make decisions based on a politician’s best interests?

What the Sensata workers really should spend their time on is pressuring state pension funds that invest with Bain (or which will be asked to invest on Bain’s new fund later this year). Make a broader economic case about how keeping 170 Freeporters employed is better for the state — and, by extension, its public pensioners — than is making a few extra dollars on Sensata.

Kind of like the pressure applied by certain Permira shareholders a few years back when it looked to shut down a Hugo Boss facility in Ohio. After all, there is no reason why Sensata, if it wanted, couldn’t simply buy the Freeport building from Honeywell and keep it open.

Not saying such a strategy would have necessarily worked, but it would have been time better spent than hounding Romney…
