From Greg Piper of The College Fix:

Elise Stefanik made history on Tuesday night, becoming the youngest woman ever elected to Congress.
The 30-year-old Republican candidate for an upstate New York district broke the record formerly held by 31-year-old Elizabeth Holtzman, also a New Yorker, in 1973โ€ฆ
It was also another night of firsts: West Virginia is sending an 18-year-old female college freshman, Saira Blair, to its Legislature, the youngest state lawmaker in the country, the Wall Street Journal reported.
Blair knocked out the Republican incumbent โ€“ nearly four times her age โ€“ in the primary and steamrolled her Democratic general-election opponent by 2 to 1.
She wants to reduce โ€œcertainโ€ business taxes and sheโ€™s pro-life and pro-gun, the Journal said, and sheโ€™ll โ€œdefer her spring semester [at West Virginia University] to attend the part-time legislatureโ€™s 60-day session and make up classes in the summer and fall.โ€
