In his latest book, Democracy and Populism, Fear and Hatred, historian John Lukacs holds that democracy is degenerating or has degenerated into populism conjoining with nationalism.
Right and left in political spectra are less relevant, although not irrelevant. Populism, once left, and nationalism, still right, are being or have been co-opted and pre-empted into right-right. Populist nationalism in the once United States of America is now labeled, framed, branded and usurped by the Republican Party.
Moving to the subtitle, Fear and Hatred, Lukacs calls hatred a right phenomenon and fear a left characteristic. Hatred can be and often is a stronger motivator. When tied to religion, hatred is easily manipulated far beyond reason. Liberal (now "progressive?") reliance on reason is more tenuous than ever.

In a 1984 book, Lukacs implied that the end of the twentieth century would see a return to barbarity...
Let us be clear, Lukacs admonishes, that the fruits of liberalism were mixed forms of government whether they be constitutional monarchies or "checks and balances" within executive, legislative or judicial branches. With legislature withered, executive triumphant and judiciary under savage attack, the once United States assumes the visage of hereditary monarchy. (pp. 14, 15)
We are also advised to maintain distinctions between democracy and liberty. In liberty, we are free to squelch democracy. Lukacs quotes post-WWII German parliamentarian Heinz Krekeler's cogent observation that ". . . a sovereign people may then again dispose of democracy and introduce a dictatorship." (p. 15)

In any case, what once may have been left or, indeed, right are no longer what they were or are now. We have nearly myriad mutations of fiscal conservative and social liberal mixed with once vocal states' rights advocates now firmly in support of situational federal usurpations (viz. 2000 and 2004 elections as well as the Schiavo frenzy, not to mention burgeoning budget, ballooning federal employment and current account deficits along with a shrinking dollar).

Lukacs emphasizes that anti-communism was the most powerful determinant of American politics as well as foreign policy throughout the twentieth century. Anti-communism was and is politically and indelibly linked with America's right, with America's conservatives, with Republicans. Liberals were not identified as anti-communist. No matter the facts.
