For the last two election cycles, Democrats have been banking on their endless harping on what they termed a “war on women” allegedly being conducted by their Republican foes. The strategy worked like a charm in 2012 against some comically flawed GOP candidates and seemed, at least to Democrats, to be a gift that could keep on giving indefinitely into the future. But like all good gimmicks, the war on women had a limited shelf life. In an unlikely development, even one of the bastions of the liberal mainstream media has noticed that the attempt to use it to batter credible conservatives is not only inaccurate but also evidence that the Democrats have run out of ideas.

Democrats went into 2014 confident about Mark Udall’s prospects for reelection to the Senate. Nor were they daunted when Republicans nominated their strongest possible contender—Rep. Cory Gardner—to be his opponent. Their optimism was based on faith in Colorado’s changing demographics that supposedly made the state more hostile to the GOP. But they were primarily counting on the utility of the war on women tactic. Wrongly thinking Gardner to be a clone of Missouri Republican Todd Akin whose moronic comments about rape and pregnancy handed the Democrats an undeserved Senate victory in 2012, liberals believed any pro-life conservative could be effectively labeled an enemy of women.

Gardner, an able legislator, rightly thought of as one of his party’s rising stars, has not been so easy to smear. But rather than re-think their strategy, Democrats have doubled down on the attacks attempting to convince voters that the personable and thoughtful Republican was troglodyte misogynist. If the polls are to be believed, the fact Udall has little to say about his own tissue-thin record and that the attacks on Gardner are as illogical as they are nasty have helped put Gardiner in the lead. Just as disconcerting for Democrats is the fact that even the leading liberal media organ in the state has also noticed that their one-issue negative campaign is intellectually bankrupt.

The reliably pro-Democrat Denver Post shocked their readers and the state political establishment on Friday when it endorsed Gardner. The paper not only praised Gardner as a source of “fresh leadership, energy and ideas” but also denounced the Democratic campaign against him:

Rather than run on his record, Udall’s campaign has devoted a shocking amount of energy and money trying to convince voters that Gardner seeks to outlaw birth control despite the congressman’s call for over-the-counter sales of contraceptives. Udall is trying to frighten voters rather than inspire them with a hopeful vision. His obnoxious one-issue campaign is an insult to those he seeks to convince.

The Post rightly thinks their state will be better served by having an influential and bright Republican in the Senate rather than a Democratic dead weight like Udall. It also believes that if the GOP controls both Houses of Congress there will be a better chance of getting things done than the current stalemate with Democrats in control of the upper body, an optimistic evaluation that probably overrates President Obama’s willingness to work with Republicans under any circumstances.

But the significance of the editorial is that it is one more indication that even liberals understand that the war on women smear is nothing more than empty sloganeering.

The country is deeply divided on social issues but, as they always have in the past, most voters are willing to agree to disagree on abortion provided the positions of candidates are rooted in principle and tempered by common sense. Gardner’s support of over-the-counter birth control is not only, as the Post points out, proof that he isn’t out to ban contraception. It’s also a sensible proposal that would eliminate the need for the government to attempt to force religious employers to pay for free birth control coverage in violation, as the Supreme Court ruled in the Hobby Lobby case, of their First Amendment rights of free exercise of religion.

The paper’s defection from the lockstep liberal smears of Republicans may be a watershed moment in American politics. After years of ignoring their responsibility to govern, Democrats may be belatedly learning that even some of their usual cheerleaders are no longer willing to acquiesce, let alone participate in their ad hominem attacks on Republicans. The war on women had a good run as a bulletproof method for rallying single female voters to the Democrats. But even the best of tactics is no substitute for a coherent economic agenda or a workable foreign policy. Nor can it allow a weak Democrat to beat a strong Republican. The race in Colorado is still close and the ability of Democrats to turn out their key constituencies should never be underestimated. But the Gardner-Udall contest may be the one that proves that liberal lies about a bogus war on women no longer work.
