I live in the US, in a traditionally republican area. I’ve seen way more Harris/Walz yard signs popping up this year, including neighbours I know have been traditionally Republican in the past. So there is hope.
American elections also include voting on issues at state, county and even town level. So yard signs encouraged vote ‘yes’ or ‘no’ on specific ballot items are also common. These issues can range from healthcare, infrastructure, education, wildlife management etc. What is interesting is that you see signs supporting the republican stance on whatever issue, next to one for Harris for president. So clearly there are people who are torn, or usually republican but who do not want Trump in charge.
I work with the public and there are a significant number of people who are concerned about the aftermath, no matter who wins. Some are the usual conspiracy theorists and doomsday preppers, but others are regular people who are worried about riots, looting etc. The company I work for has increased security until the inauguration. Pretty sure they are not the only company to do so.
