Shape Map color saturation not working

Struggling with a Shape Map for days.  I am trying to get the colors based on the Political party (Democrat, Republican, Independent). Location value is "States" which is every state in the United States. In the Legends field is "Party"(the values are Democrat, Republican, Independent). I created a measure using COUNTROWS for the "Party".
Measure = COUNTROWS(FILTER('Table','Table'[Party] = Table'[Party]) )
I dragged the count rows measure into the Color saturation field. Next, I enter the format and set the data color for Democrat, Republican, Independent. Some states show the right color, majority do not. The ones that show the proper color, are the ones in which the rows in Party column are all the same value (whether it is Democrat or Republican) for the state. If it's a mix, the countrows somehow is counting by First in the list and uses the first State coloring ex blue for Democrat.
Here is an example, the State of Texas is showing as color Blue on the map. I expected it to show as color Red since majority Party is Republican per the data. In the Excel worksheet, State of Texas has over 30 representatives, 2 are in "Senate" and the majority are in the "House" (under Congress column). Party column shows most are Republican. Maybe i'm using the wrong dax formula? I don't know... I've used similar on other Shape maps and those work for the color saturation. Not sure why this one isn't working. I appreciate your help with this!!

 

Here is a snippet of the excel

Rep1 Democrat Texas TX House
Rep2 Democrat Texas TX House
Rep3 Democrat Texas TX House
Rep4 Democrat Texas TX House

Hi @Anonymous 

 

Download example PBIX file

 

I created some dummy data for other states then I created a column to store the color for the majority party and used that as color saturation

Majority Color = 

VAR _Dem = CALCULATE(COUNTROWS('Append1'), FILTER('Append1', 'Append1'[Party] = "Democrat" && 'Append1'[State Long] = EARLIER([State Long]) ))
VAR _Rep = CALCULATE(COUNTROWS('Append1'), FILTER('Append1', 'Append1'[Party] = "Republican" && 'Append1'[State Long] = EARLIER([State Long]) ))
VAR _Ind = CALCULATE(COUNTROWS('Append1'), FILTER('Append1', 'Append1'[Party] = "Independent" && 'Append1'[State Long] = EARLIER([State Long]) ))

RETURN

SWITCH(

    TRUE(),

    _Dem > _Rep && _Dem > _Ind, 0,

    _Rep > _Dem && _Rep > _Ind, 1,

    2

)

Because the Shape Map uses color shading, the different parties need discrete values to respresent them, each one can be assigned a specific color then.

 

You can also do this with a Filled Map where I worked out the majority party (similar code to above)

Majority Party = 

VAR _Dem = CALCULATE(COUNTROWS('Append1'), FILTER('Append1', 'Append1'[Party] = "Democrat" && 'Append1'[State Long] = EARLIER([State Long]) ))
VAR _Rep = CALCULATE(COUNTROWS('Append1'), FILTER('Append1', 'Append1'[Party] = "Republican" && 'Append1'[State Long] = EARLIER([State Long]) ))
VAR _Ind = CALCULATE(COUNTROWS('Append1'), FILTER('Append1', 'Append1'[Party] = "Independent" && 'Append1'[State Long] = EARLIER([State Long]) ))

RETURN

SWITCH(

    TRUE(),

    _Dem > _Rep && _Dem > _Ind, "Democrat",

    _Rep > _Dem && _Rep > _Ind, "Republican",

    "Independent"

)

Each party being assigned the relevant color.

 

The sample file above contains all this data and both maps.

@PhilipTreacyThank you so much for this tremendous help! I have used your example and it worked with a tweak by adding the value 1 in Maximum field for the data color. I've tested it a few ways and it work exactly as I've been wanting it to. I'm still learning PowerBI and have to understand the backend functionality... Thank you, thank you for taking the time to help on this task!
