It was a major scandal that basically amounts to the wiretapping of the Democratic National Commitee. It impacted politics by ending up having Nixon being the only president to ever have resigned.
The Watergate scandal was a scandal during and after the 1972 Presidential Election. Frank Wills, a security guard, discovered clues that somebody broke into the offices of the Democratic Party and George McGovern months before the election. Those somebodies would be William Mark Felt Sr, a former FBI agent. This changed how files, documents, and wiretaps were secured better so politics can't gain an advantage over one another.
