As noted previously, five candidates had filed to appear on the Indiana Republican presidential primary, including an unknown, Patricia Sandifer. Indiana law lets anyone on the ballot, no matter if they only file one signature, if no one challenges their petition. On February 16, someone challenged Sandifer’s petition, which only has one signature on it, so she is now off the ballot. See this story.
The only remaining uncertainty is whether Rick Santorum will be on that ballot. That will be decided on February 24, when the challenge to the Santorum petition is adjudicated by the Indiana Election Commission. The only candidates whose ballot status is confirmed now are Newt Gingrich, Ron Paul, and Mitt Romney. Write-ins are not allowed in Indiana primaries, even though Indiana permits write-ins at the general election.
Which states allow write-in votes for the GOP primaries?
Michael: The Frontloading blog had information about which states allow write-in votes in the primaries for most of the states at http://frontloading.blogspot.com/2012/01/ill-see-your-white-knight-and-raise-you.html — the blog didn’t cover the earlier states in the primary season because the post was only about the possibility that another candidate could join the race at that time.
