Final answer:
The easiest way to be involved in the political process is through voting, while running for office can be considered one of the more challenging forms of civic engagement due to various hurdles.
Step-by-step explanation:
According to the Crash Course video on political engagement and the various resources provided, the easiest way to be involved in the political process is through voting. Voting is considered a fundamental form of civic engagement and a critical way for individuals to have their voices heard in the selection of elected officials and on various policy issues. On the other hand, the Crash Course material does not specify a single most challenging way to be involved, but running for public office could be considered one of the more challenging forms due to the numerous hurdles, such as the need for fundraising, campaigning, and political support.
Other forms of engagement include attending political rallies, donating to campaigns, signing petitions, and being informed by doing research about public issues. These activities enable individuals to participate in the political process beyond just voting, though some may require more effort and resources than others.
