Nothing matters more to leadership in a democracy than support for an open, honest government in which citizens are informed and in charge. It is the foundational building block of the republic upon which all else rests. And any candidate vying for the votes of the American people needs to have demonstrated a firm commitment not only to the ideal but to the reality of open government.

As we noted Tuesday, Republican front-runner Donald Trump is not one of those candidates. But neither is Democratic front-runner Hillary Clinton. Her horrible track record on transparency raises serious concerns for open government under a Clinton administration — so serious we believe they may disqualify her from public office. We hope Wisconsin voters give this issue the consideration it deserves when they go to the polls on Tuesday.

The issue immediately at hand — and under investigation by the FBI — is Clinton's use of a private email server for State Department communications. Clinton may have violated national security laws by making top secret documents vulnerable to hackers and available to people without proper security clearance. Violating those laws rightly ended the public service career of Gen. David Petraeus when he was President Barack Obama's CIA director. The FBI and Justice Department must be free to fully investigate and, if warranted, prosecute Clinton in this matter without any political interference from the Obama administration.

In addition, regardless of Clinton's excuses, the only believable reason for the private server in her basement was to keep her emails out of the public eye by willfully avoiding freedom of information laws. No president, no secretary of state, no public official at any level is above the law. She chose to ignore it, and must face the consequences.

The largest newspaper in Wisconsin sharply criticized Hillary Clinton in an editorial published Wednesday, unfavorably comparing the former secretary of state to Donald Trump in terms of her "firm commitment" to open and transparent government.

In its takedown of Trump, published Tuesday, the Milwaukee Journal-Sentinel declared the Republican front-runner "unfit to be president" by any measure. On Wednesday, the paper's editorial board trained its sights on Clinton, blasting the Democratic front-runner for the ongoing FBI investigation into her use of a private server while at Foggy Bottom and her reasons for setting up the server in the first place.
