We only need a handful. And if DACA is canceled then there will be an urgent humanitarian crisis that neither party will want to own long term. Can you imagine democrats taking the blame for not passing legislation that would protect DREAMers if DACA is terminated? Republicans will be able to say that they have laid out a solution to the DREAMers and that it's the democrats holding it up. I just don't see enough democrats holding out to stop something like this from going through.
