Question: Which of the following is NOT a potential reason for why we are more polarized as a country? People who vote in primaries have more extreme views and therefore choose more extreme candidates. Overall, voters have become more polarized in their beliefs than they were 20 years ago. Voters have become more "tribal" and less trusting of the other party. People these days vote less on local issues and more on national issues. More people live in competitive districts these days.
