GCS samples usually have a huge shortage of female respondents, so unless it's weighted, it's probably not very accurate. If it's unweighted, you're basically just seeing a poll of white men.
The OP says it's weighted to match the demographics of US adults.
Even still, if you have like 50 female respondents (which wouldn't be that weird for GCS), that's not exactly representative of the entire female population. Same for minority populations.
Dude the samples are right in the post. Just click the link. The sample is 57% male 43% female so yeah, it polls a lot more males than females.
