I think if a third party were deeply serious about wanting to establish a viable political movement. They’d try building up at the local level first, the presidency should be one of the last steps of becoming “legitimate”, the unsexy local elections are where you build up support at being treated as a serious political movement. Instead, most current third party runs tend to feel like either spoiler campaigns and/or vanity campaigns, where I’m not even sure what good it would do them on the miraculous chance they happened to win the presidency, since third parties in general don’t have much presence in Congress. There’s like four “independent” members of Congress right now, good luck getting any of your third party platform initiatives done with likely no Congressional support.
