WASHINGTON — A raft of legislation intended to better secure United States election systems after what the special counsel, Robert S. Mueller III, called a “sweeping and systematic” Russian attack in 2016 is running into a one-man roadblock in the form of the Senate majority leader, Mitch McConnell of Kentucky.
The bills include a Democratic measure that would send more than $1 billion to state and local governments to tighten election security, but would also demand a national strategy to protect American democratic institutions against cyberattacks and require that states spend federal funds only on federally certified “election infrastructure vendors.” A bipartisan measure in both chambers would require internet companies like Facebook to disclose the purchasers of political ads.
Another bipartisan Senate proposal would codify cyberinformation-sharing initiatives between federal intelligence services and state election officials, speed up the granting of security clearances to state officials and provide federal incentives for states to adopt paper ballots.
But even bipartisan coalitions have begun to crumble in the face of the majority leader’s blockade. Mr. McConnell, long the Senate’s leading ideological opponent to federal regulation of elections, has told colleagues in recent months that he has no plans to consider stand-alone legislation on the matter this term, despite clamoring from members of his own conference and the growing pressure from Democrats who also sense a political advantage in trying to make the Republican response to Russia’s election attack look anemic.
