High Quality Content by WIKIPEDIA articles! In the 19th century, a number of new methods for conducting American Election Campaigns developed in the United States. For the most part the techniques were original, not copied from Europe or anywhere else. The campaigns were also changed by a general enlargement of the voting franchise--most states began removing or reducing property and tax qualifications for suffrage (the last to remove property all requirements was North Carolina in 1856) and by the early 19th century the great majority of free adult white males could vote (Rhode Island being a notable exception, though the constitution was considerably liberalized after an 1844 Rebellion). In addition, during and after Radical Reconstruction, black males in the South were enfranchised, and technically were afterwards, though widespread voting by blacks was a practical impossibility after the 1877 withdrawal of federal troops from the South.
