Democrats in upcoming elections are likely to get a lift from President Obama’s illegal immigrant amnesty plan as more U.S. born children to undocumented migrants allowed to stay in America reach voting age, according to a new report released Thursday.

The Center for American Progress estimated that 1.5 million children and relatives of illegals who are U.S. citizens will join the ranks of voters next year and that will nearly double by the 2020 elections, likely helping Hillary Clinton if she is the nominee and Senate Democrats attempting to take control of the chamber because they are pushing pro-immigrant policies.
