One of the earliest activities party workers engage in once the general election campaign begins is

A) re-drawing each congressional district's lines.
B) forming a committee within Congress to determine campaign strategy.
C) recruiting additional candidates to run for office.
D) ensuring that citizens are registered to vote.

One of the primary goals of party workers at the start of a general election campaign is to ensure that as many eligible citizens as possible are registered to vote. This helps to maximize turnout and support for the party's candidates. The other choices are not typically involved in the early stages of campaign activities. Re-drawing congressional districts is a highly controversial process that typically occurs only once every ten years and is not part of the regular election cycle. Forming a congressional committee to determine campaign strategy is also not a common practice, as this responsibility typically falls to the party's national committee and individual campaigns. Finally, while recruiting additional candidates is an ongoing effort, it is not a primary focus at the start of a general election campaign.
