Unfortunately, Democrats don't have a great track record of passing pro skilled immigration bills either. In 2009-2010, when Democrats controlled the house and the senate as well as the presidency, they didn't bring in a single major immigration reform bill [1]. The DREAM act for childhood arrivals didn't pass the senate, and DACA was later passed through executive order in 2012. And right now some Democrats continue to oppose skilled immigration claiming that it is "racist" [2].
