U.S. now suffers from a one-party political system?

When it comes to what really matters, we now suffer under the domination of a de facto single-party state. 
That's the view of Ted Baumann in a post-election piece he wrote for the Independent Voters Network. 
With little difficulty, Baumann argues that Republicans and Democrats in Washington have melded together into an idle machine, fueled by PAC money, that accomplishes nothing other than perpetuating a non-stop, hyper-partisan stage show designed solely to gain power and strengthen self-preservation.

Here's a portion of what he wrote:

"... Few in either party seem at all interested in reining in the influence of Wall Street on our political process or stanching the massive flow of subsidies to our “too big to fail” banks through the cheap-money policies of the Federal Reserve. Although they differ over fiscal stimulus, most elected officials in both parties quietly support the ongoing diversion of trillions of dollars to bankers through market manipulation.

"(Another) example, of course, is the broken U.S. tax code. The parties claim to have vastly different agendas when it comes to corporate taxation and individual tax rates, but both work tirelessly — often in cahoots — to protect the loopholes, giveaways, and unfair disparities that are the real problem with our tax system. Millions in PAC money is their reward.

"And of course, aside from U.S. Senator Rand Paul, you won’t hear much talk of repealing abominations such as the Foreign Account Tax Compliance Act (FATCA) from either party. Even if repeal is buried in their platforms somewhere, don’t expect to see it put to a vote, no matter who runs the House and Senate.

"The election outcome probably guarantees that the next two years in Washington will be a continuous political free-for-all aimed at electing the next president."
