Why has the GOP still been able to win the popular vote in congressional elections?

The Republican Party has become more unpopular than the Democratic party on the national level. Regarding presidential elections, they've only won the popular vote once since 1988 and actually haven't ever won a majority of moderate voters since 1984. The GOP senators have overrepresented their constituents way too much. The Democratic senators represent about 40-something million more people than Republican senators do even when the US Senate has a 50-50 split. Republicans have also gotten away with having a 20-something seat advantage for US House elections, and state legislative elections due to the gerrymandering since 2010. Conservative judges on the federal level have also become really unpopular amongst the general population. Trump and the MAGA Republicans have been costing Republicans an extraordinary number of elections at both the national and state level with their right-wing extremism.

Yet, Republicans actually won the popular vote for both the US Senate and US House elections in the 2022 midterms. They also won the popular vote in both the US Senate and US House elections in the 2016 general election. Why is that?
