It's not uncommon for us to receive requests around specific design tweaks to a given public theme. Often times these tweaks are relative to a customer's industry - colors that convey a more serious tone, for example.
You'll notice the emphasis on a political color scheme and tone for these new variations. Also, being that donations are a priority action item for most candidate websites, we converted the donation item in the top navigation into a button. The intent here is to minimize the info-to-action path and, hopefully, increase donation conversions.
If you need further design customizations to your theme, be sure to reach out to an Architect.
