Now that all candidates except Trump have dropped out and/or suspended their campaigns, he is the presumptive GOP nominee. That said, there are still states that haven't voted yet, of which California is the largest.
Which candidates will still be on California's GOP primary ballot? Are candidates removed simply by suspending their campaign, or do they need to file paperwork, or is it just too late to make changes? And are any of the original 17 who dropped out much earlier still on there?
