How You Vote Is in Your Genes

'Tis the season to weigh candidates' positions, decide whether you stand on the issues, and who you'll vote for this November. But what if there's a genetic component to the way you vote? 

Brown University political science professor Rose McDermott's research shows that our political choices aren't fully our own. There is a genetic component to the sympathies and antipathies we feel. Kara Miller talks with McDermott on Boston Public Radio. 

GUEST:
