Joe Biden has won Texas’ Democratic presidential primary. The state has 228 delegates at stake, the second biggest prize of the night.

More than 2 million people had already voted in Texas even before polls opened for Tuesday’s primary. The state, which has long been reliably Republican, is growing increasingly bluer amid a demographic change in Texas.

Biden held a rally in Dallas on Monday night, when he showcased two of his newest supporters and former rivals, Amy Klobuchar and Beto O’Rourke. Pete Buttigieg endorsed Biden earlier in the night in Dallas.

Biden has also won Massachusetts, Arkansas, Minnesota, Tennessee, Alabama, Oklahoma, North Carolina and Virginia. Bernie Sanders has won California, Utah, Vermont and Colorado.
