“Trumps spent nearly $50,000 to elect congressional Democrats, they donated only $1,000 to the National Republican Congressional Committee (NRSC)....”
As for me, if I were a wealthy businessperson, I would not give a DIME to libDem politicians, just because I have principles.
As a businessperson, I never gave to politicians, but that was because I worked for them (the name - pollster - is a clue to my work). I did have to decide whether to work for liberals. Initially, I worked for the people who hired me, and I charged a premium price and then delivered premium quality answers. I moved to charging liberals 2-3 times what I charged conservatives and still getting their business. Finally, I stopped working for them regardless of price.
In business, you have a lot of obligations, including looking after the interests of investors (I didn't have any) and employees (I had a couple dozen). It would have been tough to fire someone because I wasn't willing to take liberal money. Considering how many employees Trump has, I find it difficult to blame him for participating in business the way it's done in New York under the rules he followed to make things work.
