Question

how has the internet revolutionized political campaigns?
it has drastically reduced the need for traditional forms of advertising
it has increased foreign participation in elections.
it has increased competition between candidates
it has enabled immediate communication between candidates and supporters

Explanation:

The Internet allows candidates to directly and immediately communicate with their supporters through social - media platforms, live - streaming, and email. While it may reduce some traditional advertising needs, it hasn't drastically eliminated them. Foreign participation in domestic elections is illegal in most countries and not a positive aspect of Internet use in campaigns. The Internet doesn't necessarily increase competition between candidates directly, but rather provides new tools for all candidates.

Answer:

It has enabled immediate communication between candidates and supporters.
