Lincoln gets my vote for worst prez ever, similar to Bush in many ways, he achieved some good things but had a really fucked up way of doing it and fucked up the country on the largest scale ever. Also costing more american lives than any war in american history, more than all combined with the exception of WWII. he cost more soldiers, saved fewer people, and left the country in more shit then Bush ever thought of. On the brink of the industrial revolution, the idea of slavery was ending anyways and with in 15 years it could have been ended totally in a peaceful way (with mush less resentment remaining toward black Americans or conflict between the north and south that we still see present today in some places), but no, the federal gov felt it needed to take take advantage of it and extort it to justify a war against the citizens and ideals of "united states" to assert the federal gov as a tyrannical force dictating any and all state affairs to get the control of the whole country into the hands of a few people.
I'm sure this makes me a racist to to all the fanatics on here, but you have the right to be wrong none the less, so carry on.
