Agreed also. I don't know who this "left" is that some folks here seem to think is blind to previous failings on the part of democrats/liberals, but they don't seem to be much in evidence here. Obama blew some stuff, Clinton did too. So did Adams, FDR and Reagan. That's not the point. The point is that those men - all of them - worked to better the country and did it with reasonable amounts of competence even if some portion of us don't agree with their philosophies. That's not the situation today.
Political competence is in the eye of the beholder. I think Obama failed in race relations, the economy, jobs, trade, international relations and projecting strength to protect America interests. Obamists feel the opposite. Well, that's what makes horse races.
Where Trump is different is that he is politically incorrect and says things like he sees them. Being a non-politician is what makes him attractive. Many people are tired of politicians who talk out of both sides of their mouths, the usually pablum they feed the electorate to keep the people quiet. Meanwhile, the Hillaries, McCaines, Romney's, Gores, Bushes, go about their same elite, crony capitalist ways feathering their nests along the way. That why Bush, the brother and son of two presidents, only got 5% of the vote during the nomination process. The people wanted something different not the same old BS.
Trump could turn out to be just like them, but the evidence for that is not in. In fact, just the opposite. He is pushing forward with most of the promises he made in his campaign. You may not like them, but he was elected on them and has begun to fulfill them. That's competency.
