It kind of pisses me off to say "I know they'll be a bad President" or to completely discredit their campaign without ever seeing it. You're letting your own personal feelings get in the way of giving anyone a chance and it's not okay. Dismissing someone's effort completely is insulting and an injustice to our own democracy.
As example, WritingLegend poured hours into his last campaign and the result was thousands upon thousands of words and a detailed view of what he wanted for the future. Yet because he was unopposed, the work he put into it was completely devalued and that's horseshit. We devalued hours upon hours of work, repeatedly, for what? Because a candidate can't manufacturer their own opponent? That's entirely unfair and disappointing, to say the least.
