If there are not enough women running for office, then yes, you're going to see women voting for men simply because there are no other choices.
Saying that "well, women aren't elected because women aren't running" is an evasion, an attempt to isolate the problem, treat it as if it were happening in a vacuum, rather than understand the complex cultural problems that actively discourage women from running for office, that penalize and punish those who do in ways subtle and not-so-subtle, and the fact that until very recently women in politics were not taken seriously by the the overwhelming majority of the system, were treated as outsiders and ignored.
Within living memory, there was a time when the political population of this country were almost exclusively straight cisgendered Christian white men. Women and minority politicians were notable for their rarity. To say that that's because women and minorities were just not running for office is to engage in ignorance of history bordering on revisionism. It ignores the constant, ongoing efforts made by the mainstream political machine to prevent women and minorities from running for office. It ignored decades of attempts to suppress minority votes through restrictive and discriminatory laws and regulations, and practices such as gerrymandering or closing of polling stations in minority communities. It also ignores illegal attempts to suppress women and minority voters with disinformation regarding polling and regulations, voter intimidation tactics, and outright harassment and assault.
Candidates who were women or minorities, or who openly supported women and minorities, could face similar tactics. And those who persevered and pushed through all the legal roadblocks could find themselves also the subject of disinformation and harassment campaigns. If they still managed to persevere, they could be assaulted or outright murdered by police. Look at what happened to the Black Panther Party, for one example of many.
And all these things exist to this day. Maybe not to the same extremes as they did in the 1950s and 1960s, but are still very much a problem. Gerrymandering is commonplace. Many states are still closing polling stations in minority districts, restricting hours at polling stations, and adding additional restrictions such as voter ID laws designed to suppress minority voters. The now-conservative-leaning US Supreme Court just ruled in favour of a state that is in the process of purging voter roles of minority voters. In the last presidential election, GOP campaign organizations and supporters sent out mailers and phone calls to minority voters with erroneous information on polling locations and times. Police showed up at polling locations to intimidate minority voters under the pretense of "preventing disturbances".
Minority politicians are still routinely harassed and dismissed by their colleagues. Many receive death threats. Women in politics are still subject to sexual harassment.
The barriers to entry for women and minorities in American politics are huge, in some cases nearly insurmountable. And they're going to remain that way for the near future. Parties in power are always reluctant to give up that power, and the current administration has made it quite clear the depths to which they will sink to preserve their power against any challenges.
