All of the candidates have issues with their platforms vs their performance records.
Ron Paul may have good ideas but they are so far outside the box as far as the main stream in Washington, that Congress would never allow any of his ideas that would have a large impact happen. Remember Kiddies the President can't "create" laws, or disband Government agencies. Congress needs to approve the move.
McCain....If he was the the right choice why wasn't her 4 years ago or 8? All and all he's shown time and time again not to be the best choice, in the eyes of the American and his own Parties people.
Obama, my issues is experience, he's pretty much a new comer to Washington. He's been around long enough to learn a few tricks but not long enough to know when Not to use them. On top of that I don't think Racial relations in the US are at a point where a person from the 3rd largest Ethnic Majority can win and not cause racial tensions in regions of the US. Yes that's right 3rd there are now more Hispanics in the US than people of African decent.
Clinton. Proven time and time again to be 2 faced in her stances. Nuff said.
Face it several things need to change to get the US heading in the right direction. None of the people listed above are the answer, Ron Paul doesn't display the demeanor needed to bully Congress, Obama would be used as putty by seasoned political veterans and the other two just plain suck ass. On top of it all Yours, His, Hers, and My vote mean dick as long as a Electoral College is still in place as they choose who wins not popular vote. In recent Memory this has happened people, remember that we wound up with G.W. and not Al Gore even though the final count had Gore with a larger popular vote. We're living in a corrupt system where politicians pull all the strings and none of them can be fully trusted to do whats right by the majority of the US Public.
Outlaw Lobbyist Donations, Civil Liberties Unions, and Political Parties and you can start getting America on the right track again but until that happens we're all fucked.
