For anyone still interested in this topic, we've published an update to this resource (still at https://datarepository.wolframcloud.com/resources/DW-NOMINATE-for-US-Congress). There have been a few changes in the source data structure, reflected in the updated resource, but now all the data is updated through the 117th Congress.

current = 
  Association /@ 
   GroupBy[
     Select[
      ResourceData[
       "DW-NOMINATE for US Congress"], #CongressNumber == 
        117 &], #PartyCode &][All, 
    All, #Name -> {#NominateDim1, #NominateDim2} &];
ListPlot[Values@current[[All, All]], 
 PlotStyle -> {Red, Blue, Darker[Green]}, ImageSize -> Full, 
 PlotTheme -> "Detailed"]

One more view, taking the median value by party for each congress:

median = (Median /@ 
      GroupBy[#, #CongressNumber &][[All, All, "CoordDim1"]]) & /@ 
   GroupBy[dataWithNames, "PartyName"];

ListPlot[median[{"Republican", "Democratic"}], Joined -> True, 
 Filling -> Axis, PlotStyle -> {Red, Blue}]
