Answer:
A swing state.
Step-by-step explanation:
The Democratic party refers to one of the major political parties in the United States of America. It was founded on the 8th of January, 1828 and has its headquarter in Washington DC, USA.
Also, a democratic nominee is an individual who is the flag bearer or official candidate of the democratic party by virtue of being selected by the delegates of the party. In order to become the winner of a democratic election, the nominee are expected to go around to campaign for votes from the electorates.
Thus, a swing state refers to any state in the United States of America where there are similar levels of support for the candidates of the two major political parties (Democratic and Republican party), which typically determines whether or not they would be a winner.
Therefore, a place where a democratic nominee would spend the most time campaigning is in a swing state for more votes.
