Good luck, hope you find an answer to your questions through some diligent phone work.
As an afterthought, why not call your county administration building, ask for the Supervisor of Elections department and ask them for an absentee (handicapped) ballot. This has to be done immediately as there are time limitations, and it already may be too late. So call them Monday morning. With an absentee ballot, you don't have to worry about rides to the polls and standing around for the hours the Iowa caucus system may entail.
Again, good luck.
