I am interested in what factors are correlated with ticket-splitting in the United States, particularly whether voters with low information are more likely to vote for a split-ticket.
The motivation for this question is noticing that certain states in New England, for example, Massachusetts, regularly elect Republican governors despite their entire federal congressional delegation being composed of Democrats, and 50% of voters in the state identifying as independents. This is in contrast to states such as Utah, Oklahoma or Wyoming, where this disparity has not been observed since 2010.
I have read on Wikipedia that low information voters are more likely to vote for a split ticket. Is there any available data or academic analysis which confirms this?
This is not an attack question. I just want to know if, in America, people who vote for different parties at the same election are less informed.
