Here are some concrete examples to support these points:

• A study by the Pew Research Center found that women were less likely to answer phone calls from unknown numbers than men. In 2016, only 56% of women answered calls from unknown numbers, compared to 70% of men. This suggests that polls may be underestimating the number of women who support Trump.
• A study by the University of Chicago found that people are less likely to admit to supporting Trump in a public opinion poll because they fear being judged or ostracized. The study found that people who said they supported Trump in a private survey were more likely to say they did not support him in a public survey. This suggests that social desirability bias may be underestimating Trump’s support among women.
• The Republican Party has become increasingly white and male in recent years. In 2016, 63% of white women identified as Republicans or leaned Republican. However, that number had dropped to 54% by 2020. Meanwhile, the number of Hispanic and Asian women who identify as Republicans has increased. In 2016, only 18% of Hispanic women and 13% of Asian women identified as Republicans or leaned Republican. However, those numbers had increased to 24% and 17%, respectively, by 2020. These changes in the demographics of the Republican Party may have helped to increase Trump’s support among women.

In conclusion, there are a number of reasons why public opinion polls involving female support for Trump were underestimated in the 2020 presidential election. These reasons include sampling bias, social desirability bias, and changing demographics. It is important to be aware of these factors when interpreting public opinion polls, especially when it comes to issues that are sensitive or controversial.
