I am not arguing that there not great numbers of people sympathetic to Left/liberal positions in this country - but even if those numbers were in tens of millions - we are talking about 5-6% of the population, a statistical margin of error if you will (it is a figure of speech, of course, since we are not dealing with statistical samples here).
Leaders like LePen cannot mobilize more than 10, perhaps 15% of the French electorate. Bush, who is a US version of LePen (if not worse) enjoys a sold support of about 48% of the US population. This speaks volumes how deeply reactionary the US society is. In other words - there are fascist sympathizers and reactionaries in all developed countries, but the US seem to have a much greater share of them than other countries - and there are good historical reasons for that.
The best political strategy for the Left in this country is elitist politics giving substantial influence to relatively small but vocal and well organized groups. Mass mobilization and populism can lead only to the tyranny of the majority and totalitarianism.
