The good Professor Mark Perry has the sad news for the Democratic Left who are dependent upon the unions for money and manpower to run their political campaigns.

Union membership in the U.S. fell to an all-time historical low of 11.9% of all workers in 2010, which is less than half of the 24.5% share in 1979, according to new data from the BLS.

Of course, there has to be some snark from Mickey Kaus the right-leaning Democrat.

Unions Are Latinos in Reverse: For at least a decade both the Democrats and Republicans have been lectured by journalists, strategists, and assorted members of the Bush clique that the Latino vote is growing, so they’d better do what those voters want (which, we’re told, is give illegal immigrants amnesty). And the Latino vote is growing … But not every voting bloc is doing so well. Specifically, the union vote is shrinking. According to just released numbers, the nation’s unionization rate has fallen to less than 7 percent of private sector workers, and to less than 12 percent of all workers (counting the heavily unionized public sector). The long-term trend of decline is seemingly unrelenting. To borrow a phrase from President Obama, these are yesterday’s voters! If Dems need to suck up to expanding groups, by the same logic shouldn’t they be abandoning shrinking groups?

Indeed, in California, look what the public sector unions have brought or should I say bought – a majority Democratic Party and a bankrupt state.

Tomorrow, I will post about the new illegal immigration numbers.
