His foreign policy goes against the constitution.
His universal health plan goes against the constitution
This link (Ignoring the "Hussein" part, I think that whole middle name schpeal was bullshit.) also shows a bit more info.
Really, it was more of a comment to the effect that we would need someone like Ron Paul in office, simply because he actually follows the rules set by this country's founders and anything against that is only furthering the damage done.
Obama is the exact opposite, and when their values were tested on their abilities to follow the constitution, he scored 0% while
Ron scored 100%. (the percentages are the charts with the plusses and minuses and such...)
Of course I'm not saying all of Ron Paul's beliefs are good (Guns) and I'm not saying all of Obamas plans are all that bad (healthcare (I guess... actually no-... I honestly can't decide... Obamas like plastic and Ron Paul is recycled paper. One is convenient and one is actually good for the environment (concerning decomposition and all)) but I would much rather us do a 180 on the constitution matter, no matter how scary and spooky it sounds to the people accustomed to this welfare state.
But yes, it was an attack on ALL candidates besides Ron Paul.
