Democratic presidential contenders began a frantic dash for votes on Thursday, as big-spending billionaire Michael Bloomberg sought to move past a bruising debate debut and several of his rivals jockeyed to be the moderate alternative to liberal front-runner Bernie Sanders.

There are just two days to go before the presidential caucuses in Nevada. Afterward, contests loom in South Carolina, followed by Super Tuesday on March 3, when voters cast ballots in 14 states, including California, Utah, Colorado and Texas.

The blistering attacks against Bloomberg on Wednesday night over his record on race, history of sexist comments and use of his fortune to push his way up in opinion polls — could damage his argument that he has the best chance of beating Republican President Donald Trump in the Nov. 3 election.
