I personally think the risks are less than for bank machines. But only if lessons learned in the development and maintenance of bank machines is fully embraced for the voting machines. There are some banks that let you deposit cheques without needing to type anything - they use OCR to find the amount, then verify with you, then allow you to print a copy of the cheque with the receipt. There is no reason this same technology can't be used in voting machines, with the difference being that the visual proof is kept internally instead of being printed out. That visual proof is what is needed in case of a Trump-style fishing audit.
