When it comes to younger voters, watch the margin of victory

There’s really no question Democrats are going to win younger voters in 2020. But what matters for them is the size of their margin of victory.

Republicans haven’t carried 18-to-29-year-olds in an election cycle since 1994, when exit polling showed them besting Democrats in this age group, 51 percent to 49 percent. They broke even with Democrats among younger voters in the 1998 midterms, but it’s been at least 30 years since Republicans carried 18-to-29-year-olds in a presidential cycle. …

But when the margin creeps higher, Democrats win big. CONT.
