Online "draft" efforts have been effective in the past. For example "Draft Clark" was apparently instrumental in helping woo Wesley Clark into the 2004 primary. Of course, in this case, the goal isn't to persuade Romney to run (it's obviously not his decision) -- but to encourage McCain to pick him.
A side benefit might be to continue building lists, growing supporters, and creating momentum for a future Romney for president run ...
Clearly, the "draft Mitt for VP" movement is about to begin ...
