Experts say that by 2010, if present trends continue, 40 percent of Russia’s 18-year-old men will come from historically Islamic peoples within the Russian Federation.  They will be of draft age — and also of voting age.  Their brand of Islam may be cultural and moral rather than spiritual.  Only 4 million to 5 million of all Muslims in Russia are said to regularly practice their religion, experts say, although the higher birthrate of Muslims means they are likely to become more visible and active in politics.
