I agree that third party candidates should be in the debates. But I cannot support Johnson.  I've done some research into his platform.  On some issues, like federal spending, his website is annoyingly vague.  On other issues, I disagree with him.  But I looked deeper. 

As Governor of New Mexico, he vetoed spending for youth suicide and domestic violence prevention, early childhood literacy and alternative education programs for high school dropouts.  But the New Mexico budget grew by nearly 5% under his leadership.  He told the Wall Street Journal that Social Security needs to be privatized, the retirement age increased, and benefits should be means tested.  He said in an interview that he'd cut everything in the federal budget by 43%, including Medicare and the military's ability to go on the offensive against our enemies. 

I'm also not thrilled that he placed more importance on climbing mountains and running marathons than working to strengthen his first marriage.
