Pandering to small business (along with every other interest group) seems the politicos present modus operandi. They promote small business as a massive engine of job creation.
But, as Dean Baker notes, "There had been some debate in the 90s about whether small businesses were responsible for a disproportionate share of job creation.

As a result, small businesses on net, create new jobs at roughly the same rate as larger businesses."
