Alexandra DeSanctis uses a National Review Online column to push back against the argument that sexism is hurting Democratic presidential contender Elizabeth Warren’s campaign.

Warren now sits at just 14.8 percent in the RCP average, in third place behind Bernie Sanders, with about half the support Biden has. The former vice president has lost a step or two (or several) since his time as Obama’s right-hand man, but it’s looking less and less likely that Warren will be the Democrat to supplant him as the party’s favorite heading into 2020’s early primaries.

For media observers who have been pulling for Warren from the start of her campaign, there can be only one plausible explanation for her fall from grace: sexism. …

… But if sexism really were to blame, why would Warren have spent several months as the race’s second front-runner, in close contention with Biden? What few on the left appear to have considered is the possibility that Warren’s policy positions and recent blunders bear the most responsibility for her declining popularity.

Over the last several months, Warren has stumbled — and not because voters discovered she’s a woman.

There was this report puncturing her narrative about having faced pregnancy discrimination. There was her false response to a question about whether her children had ever attended private school. And there was her repeated refusal, during the last debate before her Medicare for All rollout, to say whether her plan would raise taxes on the middle class, along with her subsequent falsehood that it would not.

But the best explanation for Warren’s decline is her Medicare for All plan itself, and her drop in the polls is clearly correlated with its rollout.
