Most surveys of web use show a fairly even gender balance online, but political blogging is dominated by men. One exception is Michelle Malkin, a conservative newspaper columnist and author with one of the most widely read conservative blogs in the US. That makes her one of the most influential women online. Her main theme is how liberals betray America by being soft on terrorism, peddling lies about global warming and generally lacking patriotism and moral fibre.
