The six states won by Clinton –Alabama, Arkansas, Georgia, Tennessee, Texas and Virginia — held a combined 571 delegates, compared to the 288 delegates of Sanders’ five target states — Colorado, Minnesota, Massachusetts, Vermont and Oklahoma.
The Democratic contests award delegates proportionally based on votes, and it takes 2,382 delegates of the 4,763 total delegates to win the party nomination.
Clinton’s six victories so far on Tuesday night solidified the sense that she would be the Democratic Party’s standard-bearer this summer.
Speaking at a rally in Miami, Florida, Clinton appeared to be eyeing the general election as she blasted the Republican front-runner Donald Trump.
“It’s clear tonight that the stakes in this election have never been higher and the rhetoric we are hearing on the other side has never been lower,” said Clinton.
So far, Sanders has projected to win two victories in his home state Vermont and Oklahoma, and was locked with Clinton in Massachusetts, a state he must win on Tuesday.
On the Republican side, Trump was declared winner of the Republican primaries in Massachusetts, Tennessee, Alabama, Georgia and Virginia while Senator Ted Cruz won two states, including his home state Texas, which held 155 Republican delegates.
To win the Republican nomination, a candidate must win at least 1,237 of the 2,472 total delegates.
As many as 12 U.S. states and American Samoa took part in Super Tuesday contests this year, as Clinton and Trump, both of whom won three of the four early-voting contests in February, looked poised to cruise to party nomination after possible sweeping victories on Tuesday.
