Money is more fungible than votes. If you live in a very red or very blue state, it's probably more impactful to buy $100 worth of political advertising for your candidate of choice in swing states than it is to actually vote in a nationwide general election. (For what it's worth, I'd bet this is still true if you replace $100 with $1.)
