1. He is a wicked and racist man and yes, his action would be dictatorial.
2. I can't imagine a patriotic Obama, but to answer your question an unilateral action in the interest of the country would be to uphold the Constitution with its original meaning. That, I would call patriotic.
After I wrote the comment, I thought Patriotic Obama? What a contradiction, or total oxymoron! He is one leader that has ALWAYS took sides against the American interest, with the one exception I can think of as killing OBL, or authorizing drone strikes.
If we, due to the dilution of American voters by the importation of non-Americans cannot vote in another leader who will look out for American interests, then a long, painful decline is inevitable. In that case, a patriotic strong man or woman may be desirable.
Democrats and Republicans have a vested interest, not just in looking out for themselves and their cronies, but in making good decisions, i.e. securing the border, handling debt, maintaining a strong military, restoring American industry and jobs, etc. in order to prevent this from happening.
