An aide from a rival campaign not affected by impeachment noted that in addition to the obvious downside that candidates would not be able to campaign in the state, it would also make it more difficult for them to get local news coverage. The aide argued that “it gets a lot more important to be on local news in Des Moines or Cedar Rapids rather than being on CNN or MSNBC” in the weeks before the caucus.

Candidates who can afford private jets can still zoom in and out of the state for some evening events in Iowa. For example, Sanders is now scheduled to hold a rally on Wednesday evening in Cedar Falls, Iowa. However even with private jets, the trial schedule limits the amount of retail politicking any candidate can do in a state where caucusgoers notoriously like to interact with candidates.

All of the campaigns will be using surrogates, tele-town halls, and Skype events to reach out to prospective voters. The bench of surrogates varies from candidate to candidate. Klobuchar’s underdog campaign will bring out Minnesota politicians like Tim Walz, the state’s governor, and the mayor of Minneapolis, Jacob Frey, to stump in Iowa. Warren will be able to use former presidential hopeful Julian Castro and Representative Ayanna Pressley of Massachusetts, among others, as substitutes.
