You can tell Trump is very very careful how he spends money.
All the other candidates spend it as if they did not earn it like children would.
The other candidates live in fantasy with play money.
That’s how it looks to me.
It’s in Trump’s blood to spend money frugally. Sure, if he want’s something that costs money, fine, but he sure doesn’t blow it when he doesn’t have to.
If he can run a campaign on a shoe-string, he does it.
If he can get free publicity, he gives cause to obtain it.
He’s a crafty old fox.
