A federal judge on Friday blocked President Donald Trump’s attempt to overhaul elections in the U.S., siding with a group of Democratic state attorneys general who challenged the effort as unconstitutional.
The Republican president’s March 25 executive order sought to compel officials to require documentary proof of citizenship for everyone registering to vote for federal elections, accept only mailed ballots received by Election Day and condition federal election grant funding on states adhering to the new ballot deadline.
Judge Denise J. Casper of the U.S. District Court in Massachusetts said in Friday’s order that the states had a likelihood of success as to their legal challenges.
“The Constitution does not grant the President any specific powers over elections,” Casper wrote.
In fact, it defines exactly who has those powers:

The president gets no say at all in how elections are conducted. The states determine that, except that the US Congress can determine the election day & time.
