The web search results discuss the partisan leanings of Gen Z and the differences between younger and older voters, but none of the provided sources make the specific claim that 'America's youngest voters are far likelier to vote Republican than their older siblings.' One source notes that 'each younger generation is leaning more democratic than the last, until recently with young Gen Z voters overwhelmingly mo' [sic], while another mentions young Republicans caring about 'cancel culture,' but no source directly compares the likelihood of the youngest vs. older siblings voting Republican.

The evidence provided only contains general definitions of 'backlash' from multiple dictionaries, but no source directly links a 'backlash to COVID-era policies' to a measurable political shift causing 'many younger voters to shift politically to the right.'

The web search results confirm that Gen Z uses social media extensively, mentioning platforms like Facebook, Twitter, and YouTube. However, none of the provided sources specifically state that 'Older Generation Z members came of age using platforms such as Instagram and Twitter' as a definitive statement about their formative years.
