Guerilla countermove: give $199 to a number of candidates instead of $200 or more to one. Nothing need be reported.
I know of one well-known Dem Congressman who systematically does this.
Better yet.
Donate in the form of anonymous gift cards, each under $200. I am pretty sure you can “same as cash” gift cards.
That's a common tactic and yes, it does get reported if it's systematic (repeated by the same individual.) FEC reports would easily catch that.
Just like withdrawing $9,999.99 from a savings account repeatedly every month. If you think you're side-stepping the AML laws by taking out less than $10k all the time, think again.
