Final answer:
The availability of the Internet and social media has made it difficult for American politicians to deny previous statements they have made, as videos can be immediately posted online and candidates can directly connect with people through social media. Regulations, such as the Bipartisan Campaign Reform Act, require candidates to take responsibility for their advertisements.
Step-by-step explanation:
The availability of the Internet and social media has made it difficult for American politicians to deny previous statements they have made. Videos can be immediately posted on the internet, allowing people to hold politicians accountable by revealing their contradictions and falsehoods. For example, Hillary Clinton had to admit she had misremembered when videos on YouTu be showed that her claim of being under sniper fire in Bosnia was false.
In addition, social media platforms allow politicians to directly connect with the people, bypassing journalists. Candidates can now respond to accusations and share their message with millions of viewers online.
Furthermore, regulations have been passed to require transparency in campaign financing and donations. The Bipartisan Campaign Reform Act of 2002 (McCain-Feingold) requires candidates to include a recorded statement within their advertisements, stating that they approve the message. This makes it difficult for politicians to distance themselves from negative or false advertisements.
