I may just be biased to the original version b/c it is the original, but leaving out the “for” seems awkward. I still get it and think it’ll be just as effective, but it’s hard for me not to want to say “for”.
“Vote better” & Vote orange” flow off the tongue nicely, especially if you’re going for an alternative to “vote red/blue” but they might lack a little context when leaving out “money”.
I’m a fan of both. The simplicity of the message and design can be powerful.
You could also make a variation of the “I voted!” sticker too, and maybe make it into a real pin or badge. I’d wear that every day!
Keep up the good work!!!
