In a resounding rebuke to presidential overreach, a Massachusetts federal judge has decisively thwarted President Trump's endeavour to unilaterally reshape US electoral processes, siding with a coalition of Democratic attorneys general who cogently argued the initiative's inherent unconstitutionality; Trump's executive diktat, promulgated in March, which sought to impose stringent citizenship verification mandates for voter registration, stipulate the absolute acceptance only of postal ballots received precisely by Election Day, and tether federal election subsidy disbursement to states' acquiescence to this newly imposed temporal constraint, was met with staunch judicial resistance, notwithstanding the White House's contention that the order aimed to safeguard "free, fair and honest elections"; Judge Denise J. Casper, in her meticulous ruling, asserted the high likelihood of the states prevailing in their legal challenges, emphasizing the Constitution's conspicuous absence of explicit presidential prerogatives regarding electoral administration, and definitively enjoined enforcement of the provision mandating the summary rejection of any mail-in or absentee ballots arriving post-Election Day, marking the second judicial setback for Trump's electoral manoeuvre, following a previous injunction against segments of the directive issued by a Washington D.C. court.
