One out of every four Latino voters today said that they had never voted in a midterm election before, according to early results from the NBC News Exit Poll. The share of first-time midterm voters was nearly one in five among African American voters and one in 10 among white voters. 

In addition, a majority of voters under 30 — a group whose participation in elections generally lags behind that of other age groups — said that they voted in a midterm election for the first time this year.
