We can’t teach kids to be so cynical and pessimistic as we are…
If I were you, I’d just say something neutral, like “these are two smart, accomplished individuals who have slightly different proposals for taking the country forward.” You can add that you don’t find any of the two candidates convincing enough, and that you may vote for a third party or independent candidate.
N.B.: I know, folks who are committed to one party or the other won’t agree with the use of the word “slightly” above. The politically aligned would want us to believe that their guy is not only the best, but the only viable choice, and that if we elect the other guy, our country would surely collapse. But I digress…
