In Pennsylvania the man whose party ran the xenophobic anti-China attack ads for him loses… to the man who voted for a constitutional amendment banning gay marriage and voted to outlaw adoption by gays in D.C. There is no party for liberty.
Both parties are equally willing to prevent voluntary exchange, it’s just a difference of opinion between what constitutes too offensive, or when autonomy is legitimate. To Republicans, a prostitute selling her services is either too offensive or being taken advantage of. To Democrats, a low-skilled worker selling his services for less than the minimum wage is either too offensive or being taken advantage of. The arguments and disregard for liberty are often the same in either circumstance.
