I’m not naive.
But I do believe in the three theological virtues.
By the way, despair is a sin.
Despairing of the future of one's country may in fact be entirely appropriate in some circumstances.
The sin of despair is committed when loses hope of salvation; it has absolutely nothing to do with an observation one makes of a temporal situation he or she faces. (There were many martyrs who faced their deaths with the full knowledge that their obstinacy in clinging to the Faith would cost them their lives; nobody would have considered these men or women to be guilty of the sin of despair.)
If a country could undergo a change of government through a coup, then there is little reason to expect that the beneficiaries of this coup would ever feel so inclined to alter the mechanics of the third-world voting process that could allow such a coup to take place. It's not desperate to point this out; it's merely an observation.
And while we may hope that we can turn around such a situation in the next four years, the hope that we refer to here is merely a temporal hope; it has nothing to do with the theological virtue of hope that you refer to (which, of course, pertains to the hope of our own salvation). The survival of the Republic of the United States has absolutely nothing to do with the state of the Bride of Christ, which stands on its own with the protection of the Holy Spirit.
And while many Catholics in the country have adopted the Protestant view that there must be something divine about the American Experiment, we know that this is simply not the case; a country that could allow the murder of more than 60 million of its most vulnerable citizens over a period of almost fifty years is as weighed down by original sin as any other.
