Bro the only metro areas that matter are NYC, SF, DC, LA, Boston and Chicago (all six are very blue), the major Texas cities (OK so Houston and Dallas are two red cities, but Austin is blue and the majority that were previously mentioned are still blue. Technically El Paso and Laredo are also blue towns and they play a big role in cross-border produce), and during produce season - Atlanta (Atlanta is a blue city in a red state).
The rest of the US are fillers
