Even though the Soviet Union used their definition of atheism to control the population, states and kingdoms governed by Christianity (such as Tudor England) typically control/controlled people's lives to a much greater extent. The Catholic church is a more than adequate example of this.

The freedom to practice your religion of choice is a secular characteristic of government. A true Christian state would have to enforce the dictatorial "Thou shall have no other gods before me" rule. Anything else would be a secular ruling, which is closer to atheism than Christianity.

I'm not sure if the intended meaning of this question is if Obama should be "kicked out" by means of impeachment or by the lack of a second term, but I'll just assume it's the latter.

If the only alternative to Obama is a guy who makes claims like "corporations are people too", my answer is absolutely not.

Unless your brother is a member of Congress, his vote is inconsequential. Al Gore won the popular vote in 2000 by over half of a million votes, he didn't become president. Based on that, the only conclusion I can only come to is that 51,000,000 votes (the majority of votes for that election) didn't matter. There are better ways to spend his time.
