Some quotes that explain in words better than mine why I will not vote for anyone but Ron Paul.
"We engage in the election the same as in any other principle: you are to vote for good men, and if you do not do this it is a sin: to vote for wicked men, it would be sin. Choose the good and refuse the evil. Men of false principles have preyed upon us like wolves upon helpless lambs. Damn the rod of tyranny; curse it. Let every man use his liberties according to the Constitution. Don’t fear man or devil; electioneer with all people, male and female, and exhort them to do the thing that is right. We want a President of the U.S., not a party President, but a President of the whole people; for a party President disfranchises the opposite party. Have a President who will maintain every man in his rights.” (Hyrum Smith, Source: History of the Church, Vol.6, Ch.15, p.323)
"I will tell you whom to vote for: we will vote for the man who will sustain the principles of civil and religious liberty, the man who knows the most and who has the best heart and brain for a statesman; and we do not care a farthing whether he is a Whig, a Democrat, a Barnburner, a Republican, a New Light or anything else." ( Brigham Young, "Discourses of Brigham Young" pg. 358)
You see supporting Ron Paul was never a matter of beating Obama. It has always been about voting for the candidate who was right. Johnson is not as bad as either Obama or Romney. But that is not a reason for me to support him. I can understand why others would vote for him. And I support you in that. In any other year I might vote for him. But in a year where I have a chance to vote for someone like Ron Paul, even if it is in a uncounted write in, I cannot do anything less. This year I don't have to compromise my beliefs to choose a politician to support. I can vote for Ron Paul. And I will.
