The conclusion here doesn't quite follow from the premises :). Obama didn't do what he said does not imply vote for Trump any more than it implies vote for tajen.

Now I'm going to delve into specific politics more than I normally like to do, but I think there are important ideas to consider. Even if a president doesn't do what he/she promised to do, the attitude of a president does have an effect on the country. Judging from the attitude of Trump and the raucousness of some of his rallies, I don't think Trump's attitude and that of his more violent supporters should be spread across the country. That alone is enough reason to vote for someone other than Trump.

It's pretty sad, though, to have several elections in a row where more and more people are voting against a candidate rather than for a candidate. I can only think of one current candidate who I would vote for positively, rather than to just to avoid another candidate who is more negative.
