One can still cast a protest vote. The other two alternatives aren’t so great, either.
Yeah, not so great, but at least they’re pretty sure that 9-11 wasn’t an inside job.
You get two choices, Perry and Hutchison. You can write-in Calvin Coolidge if you wish, but all that will do is keep Perry under 50% and pit him against KBH in a run-off in which write-in votes will not be counted. So you need to choose which one of the two is better, or less bad, unless you want to sit this one out.
