In the fight for Massachusetts Senate seat, it's an epic battle, between Republican incumbent Senator Scott Brown against Elizabeth Warren, the liberal crusader famous for taking on Wall Street.
The outcome of this race could decide the control of the United States Senate.
ABC News recently sat down with both candidates while out on the campaign trail in the fever pitch leading up to Election Day.
No Senate race in the country has been more expensive and more personal.
This contest is the most expensive Senate race so far in terms of money raised with both sides raising over $50 million total. Spending is very high as well- over $33 million has been spent, the second most expensive in the country, a figure underscored by the fact that both candidates made a pact in January agreeing not to accept advertising by outside groups.
