Expression help needed for lower third

[JTBKY]

Hello! 

I am creating a lower third and eventually I want to turn this into a morgt file as well.  

But my problem is the lower case letters are messing up the white and blue bars. I need both to be a fixed height.  Lowercase j's and g's and some i's make the white and blue bars to be perfect height. I need that to be a fixed height when I don't have j's and g's.

Also if there is a way to add room for the logo on the left to be apart of this expression I am all in.  As of now I have it working but the file is janky and isn't the best. 

I've attached some video examples to show what I am doing here.

Simply dial in fixed values and only use the sourceRectAtTime().width to adapt it to the length of the text. No need trying to be smarter than a Vulcan.

I've found that I get much more predictable results with Essential Graphics and text expressions by setting the text on a "hidden" text layer, then using a visible text layer with the expression on it, getting the text from the hidden one's source text property.

At one point, expressions didn't seem to work at all with EG text, so I'm guessing the issue is connected to the order AE processes things in.
