DACA or not

Presidents use executive orders when they cannot get congress to pass laws they want. The downside is that the next president can negate these orders. When this happens the court steps in and the results show that Carter won 68% of his challenges, Reagan 75%, Bush 41 77%, Clinton 63%, Bush 43 60%, and Obama at 45%. One of Obama's orders called DACA is being reviewed by the court. The congress refused to pass this into law and now Trump is asking the court for review. Trump does not want to deport these people but wants to use it as a bargaining chip to negotiate immigration reform.
