There's a tendency once people give to a candidate to stick with that candidate. So, if Donald's asking for money, too, it might stop people from contributing to someone else.
The best way to contribute....buy some campaign gear from his store. FWIW, I ordered a made in the USA 100% cotton tee shirt for $20. Some of the clothes have polyester, some are all-natural. All are made in the USA. Won't it be great to see the USA blanketed with Trump campaign gear?
To me, the Donald asking for money is like the Pope asking for Communion wafers.
