Why may Turnout be Falling at Elections?

-Disillusionment with the Parties, Seen in younger People. Also less Commitment to Parties -People caring more for Single Issues then Broad Policies -Lack of Disintiction between the Parties since the 1990s -Electoral System [FPTP] having Large Wasted Voted [Smaller Parties and Safe Seats] and Unequal Value [Marginal vs Safe] -Emergence of Referendums [Direct Democracy?]
