My grandfather taught me at an early age that the two topics that you don't bring up in mixed company is politics and religion. For one, it will ALWAYS cause an argument, and B, that argument will not be won by either side.
That being said, since I didn't bring it up, I'll put my $3.44 in. (It used to be 2 cents, but with inflation and all......)
Every president has his good qualities and his bad qualities. Roughly 50% of the population is going to disagree with most of the presidents decisions on principal. In this case, its the 50% that are Republicans. Six years ago, it was the 50% that was the Democrats. Either way, its not just the president that causes all of our problems. The congress, the Senate and the president are all pretty much jacked up. And why is that? Because of bi-partisanship. The government was set up to elect individuals to represent the people that elect them. That stopped happening a LONG time ago. They no longer listen to their people, but instead go with what they THINK their people want, sometimes. What usually happens, the elected vote the way their PARTY wants them to vote. It's a vicious cycle that doesn't appear to have an end. And it may not. As long as people vote for the party and not the individual, the cycle will continue.
Look at the Libertarian party. Yeah, they have a couple of congressmen, and I think 1 or 2 senators, but its not enough to make a difference. But if you listen to what they have to say, most people, Republican AND Democrat, agree with their way of thinking. Less government, more freedom, less spending by the government, allow free enterprise to be free enterprise, with the risk of failure or the risk of success. Let the market drive the markets, not the government, not the lobbyists, and certainly not the political influences sitting in the seat next to them. But people won't vote libertarian because they either don't know what they stand for, because they don't spend the money that the 2 primary parties do, or, they think that they are wasting a vote.
By the way, I think Obama sucks. But...... So did most of the other recent presidents.
