At a glance: Super Tuesday states and delegate counts

Former vice-president Joe Biden won at least eight large states on Super Tuesday but his main rival Bernie Sanders is on pace to pick up four, including California, the biggest prize of the night.

With partial results in from all 14 Super Tuesday states and one US territory, Biden was forecast to win at least 247 delegates, with Bernie Sanders getting at least 179, Elizabeth Warren nine, Michael Bloomberg eight, and Tulsi Gabbard one.

Here is a quick look at what is happening on the ground after the 14 states and one US territory voted to choose a Democratic challenger to President Donald Trump in November.

CALIFORNIA

Delegate count: 415

Media reports projected Sanders would win the state. Sanders will win at least 48 delegates.

California was one of the most closely watched states because of its 415 delegates. Sanders was hoping to drive up big margins and amass an unsurmountable lead in delegates, while Biden was hoping to remain close enough to prevent a blowout.

The polls closed at 11pm. EST (0400 GMT Wednesday) but voters who were in line were still allowed to vote.

TEXAS

Delegate count: 228

Media organisations projected Biden to win Texas.

With about 90% of precincts reporting, Biden led with 33% over Sanders with 29%. Both men will win at least 20 delegates.

Sanders had been heavily favoured to win in Texas but Biden invested heavily in the state and was banking on a late surge. Former New York Mayor Bloomberg had massive spending in the state and appeared to be taking a share of the moderate vote, and with more than half the precincts reporting was in third with 16% of the vote.

The polls closed at 8pm. EST (0100 GMT Wednesday).

NORTH CAROLINA

Delegate count: 110

Biden won and will secure at least 35 delegates. Sanders will win at least 15 delegates.

VIRGINIA

Delegate count: 99

Biden easily won Virginia and secured at least 49 delegates. Sanders will win at least 19 delegates. Warren will take at least one delegate.

The polls closed at 7pm. EST (0000 GMT).

MASSACHUSETTS

Delegate count: 91

Biden won and is projected to secure at least 22 delegates, Sanders 16, and Warren eight.

Warren had once been considered the favourite in the state she represents in the US. Senate. Sanders was considered her biggest threat. But Biden's surprise victory — after spending no money there nor deploying any staff — solidified his big night.

The polls closed at 8pm. EST (0100 GMT Wednesday).

MINNESOTA

Delegate count: 75

Biden won and will pick up at least 17 delegates with Sanders winning at least nine.

Senator Amy Klobuchar had been favoured to win her home state of Minnesota. But on Monday, she ended her campaign and threw her support behind Biden.

The polls closed at 9pm. EST (0200 GMT Wednesday).

COLORADO

Delegate count: 67

After Biden outperformed him in the South, Sanders is hoping states like Colorado will fuel a Super Tuesday advantage.

TENNESSEE

Delegate count: 64

Biden won and will secure at least 18 delegates, while Sanders is in second place will win at least 8 delegates.

With no opinion polls assessing the Democratic primary in the state, campaigns were banking on trying to capture a surprise win there. Bloomberg invested heavily in time and resources, while Biden hoped his support among African Americans would carry him to victory.

The polls closed at 9pm. EST (0200 GMT Wednesday).

ALABAMA

Delegate count: 52

Biden won easily and will secure at least 17 delegates. Sanders will win at least 3 delegates.

Delegate count: 31

The polls closed at 8:30pm. EST (0130 GMT Wednesday).

UTAH

Delegate count: 29

Sanders was projected to win the state and secure at least 3 delegates.

The western state has traditionally been conservative, but liberal pockets in places like Salt Lake City and Park City could prove beneficial to Sanders. Two opinion polls conducted earlier this year found him with a lead.

The polls closed at 10pm. EST (0300 GMT Wednesday).

MAINE

Delegate count: 24

After polls closed, the state was too close to call, with Biden and Sanders running neck-and-neck and Warren in third place. Both Biden and Sanders will win at least four Maine delegates.
