CMV: It doesn't matter who you vote for in America.

There's really only two parties, both controlled by the corporations of America, and thus all the decisions made by the president are ultimately filtered through the CEOs and heads of financial institutions. It doesn't matter who you vote for since the president is not powerful enough to make a real change in the country. Hence voting is meaningless. It's all a sideshow for the schmucks that believe in "democracy" even though America is in fact a republic.

Nothing will change in America because people keep voting for the two same parties. The only people that can change America for the better are the people themselves, not the leader. If Americans don't like military spending, then they should shame the military, if they don't like the way healthcare works, then shame the people who run the healthcare, not by voting and going around doing all the congress bullshit.

All this is abstract. Let's get some specifics. 

Do you really believe that if Al Gore had been elected, we would have fought the Iraq war? Do you think he would have repealed elements of the clean air act and called it "operation clear skies" as Bush did? 

Do you think Ford would have let Iranian hostages linger for a thousands days without bombing, as Carter did? 

Do you think Republicans and Democrats have the same chances of raising taxes on the rich?

There are major differences between candidates, parties, and platforms. These differences, from nuclear proliferation and  funding and support of other nations to research priorities like Stem cell research, effect millions of lives.

The "there's no difference between the parties" trope is more likely the result of people, preferring the lazy luxury of apathy, writing off participation in the difficult and emotionally unsatisfying political process.
