He lives to keep score (when he's winning).
Sure
A driven individual.
Yes you could say that. Problem is what it is that drives him.
For example, Sessions is by all accounts enacting Trump's agenda in Justice (to the detriment of the US and what it stands for...) and yet he has been "driven" to berate and insult and openly discuss his firing why? All because he recused himself in an investigation into
Trump, will not insulate the "President" into an investigation in to the campaign of
Trump , showing insufficient loyalty to
Trump, and can do nothing to prevent State and Federal investigations into the shady business dealings of
Trump.
We get what drives Trump. Its not something to be admired.
