(CNN) President Joe Biden took his first big trip as president this week when he went to Wisconsin for a CNN town hall . Wisconsin was the state that put Biden to the 270 electoral vote threshold in the Electoral College . A swing state index close to zero in any election means a state is really important in a given presidential election. Wisconsin has maintained its swing state status, even as coalitions within the state have changed dramatically. Biden won in large part by crushing it in Dane (which contains Madison) and Milwaukee counties.
