Is it election fraud or otherwise against the law to call a leaked caucus hotline being used for election?

Question

Part of the media's narrative for the Iowa caucus is that pro-Trump pranksters/trolls from 4chan prank called the Iowa caucus locked up the phone lines preventing the redundant system from assisting when the app failed.

• If a number is released online expressly for the purpose of phoning in election results,
• And, if you knew that and intentionally tried to lock up the line

Did you commit a criminal act, and can you be changed?

Answer 1

There seems to be no current applicable prohibition state law in Iowa in Iowa Code 39A, the Election Misconduct and Penalties Act. It is also not at all clear that precinct caucuses count as "elections" as applicable to the sections with criminal prohibitions (the precinct caucus does not appear to constitute a "primary election" under Iowa law).
