Median voter theorem

Median voter theorem is a way of explaining the outcomes in a two way race majority rule system where positions exist along a spectrum. Whichever position or candidate the median voter agrees with will be the winner. Everyone from the left will choose the left most choice or candidate and everyone from the right will choose the right most candidate, So whichever side the median voter falls on will have 50% or more of the vote. In this way in an up or down approval measure a candidate can get well below 50% approval, if they are not sufficiently far left for the left wing and right for the right wing, but when challenged from either side by a candidate that does approve to the more polarized voters the side with out a candidate will rally to the aid of the unpopular candidate rather than seeing the more polar candidate from the other side win; this is how George W. Bush won in 2004 in spite of his liberal voting record.[1]
