At a national level, Senate Democrats have been trying to pass laws that place general limits on the practice. It would be nice for "both sides" arguments if some version of this project enjoyed bipartisan support: unfortunately it does not.
I don't think the federal government has the authority to stop states from gerrymandering? Am I mistaken? It seems like the Democrats are just virtue signalling.
I think the "elections clause" (Article 1, Section 4, clause 1) gives Congress broad authority to override state laws regarding how its own representatives are elected. (Note: edited to simplify...)
I am aware of that clause but I am not sure I interpret "The Times, Places and Manner of holding Elections" as the same thing as drawing district lines.
