Anthony Downs Ch. 8 The Statics and Dynamics of Party Ideology
Learning Objectives • Evaluate how people develop political opinions and how this impacts their political behavior. • Understand the decision making process for why people vote as they do and how this changes over time.
Party Movement • When do parties change ideologies • When do the diverge? • When do they resemble each other
Where To Build a Bar in Central Texas? Here… in Bastrop
Or Here? 6th Street
Lets Apply this to Ideology • Here is a distribution with 0 representing policy liberalism, and 100 representing policy conservativism • A and B represent political parties
Where Parties Should Go in A Normal Distribution They Move To the Center
Why go to the Center • You Cant leapfrog the other party • More voters • At what point do you stop moving to the Center?
The Problem of Being Too Moderate • A Third Party could grab your flank • Too many of your people stay home
A Polymodal System • In PR systems, 1 party for Each hump • How might this differ in a Single Member District System?
Party Movement in Multiparty Systems • Stay Put! • Distinguish yourself from your enemies
How our Parties Deal with the Humps • Social and Economic Conservatives (within the GOP) • The Many Humps within the Democratic Party
New and Old How Many parties
How Many Parties in Majority Elections • Duverger’s Law • Mechanical Effect • Psychological Effect
How Many in a Two Round System • If No candidate gets 50%+1, we have a runoff • This system encourages multiple candidates/parties as well as coalitions
The Kinds of Candidates • Those who are there to win • Perry • KBH • Those that are there to influence • Medina • The rest • This system encourages populist and extremist candidates
Voting in the First Round • Try to get your preferred candidate into second place or Get them 50% • Do not worry about switching candidates
The Second Round • Round 1 winners must compromise to get the supporters of the losing candidates in round two • This favors candidates who are situated at the political middle • This hurts intransigent candidates
Rational Voting in this system • Round 1 with your heart • Round 2 with your head
How many parties in a PR system • As many parties as humps exist • Depends on the threshold
Getting New Parties • Existing parties cant jump over each other • New Parties come from • Between the gap • On the fringe
What New parties Want to Do Win elections Threaten Existing Parties
How can Third Parties Win? A Shift In Franchise…. The electorate changes!
Ambiguity • You can try to accomplish everything • It increases your appeal • It makes it harder for the voter to be rational! Why?
