Yes, but they are both just different sides of the corporatist party. They divide on talking points, they each use a different flavor of spin to achieve the same objectives.
Look at healthcare for example. The US spends more tax dollars per capita providing no healthcare to it's citizens than most nations with total healthcare (including dental) spend per capita without providing notably better care according to any real objective metric. Implementing real state health care neither requires outlawing private medicine nor increasing taxes. The republicans lie saying it requires both, that's their flavor of spin, the Democrats also lie and promote models that both increase taxes AND funnel money to insurance companies.
Both flavors of spin are targeted at the same result, increasing profits for the big private medical industry at the expense of the citizens. It doesn't matter which rhetoric you buy into, they are just different spins on the corporatist agenda. There is no populist party in the United States and if there were they'd get no substantial mainstream media coverage or if so popular it couldn't be avoided would be a Ron Paul comical and dismissive spin on their coverage because the mainstream media is run by massive corporations.
If you pay attention you will see the "two parties" are divided on very very carefully chosen lines.
