Party affiliation reliably predicts how state court judges decide cases

Evidence

Judicial elections can directly affect judicial decision making only if there are competing candidates and voters can distinguish between their orientations. In nonpartisan elections, these conditions are often not met. In partisan elections, party labels can serve as indicators of general orientation: Republican candidates are more likely to be conservative; Democratic candidates, liberal. Studies of voting behavior in state courts by and large confirm that party affiliation is a fairly good predictor of how judges decide. — G. Alan Tarr, Judicial Process and Judicial…, 432
