DONALD, BERNIE PUT RIVALS — AND PARTIES — ON NOTICE

Trump wins big in Michigan, Mississippi; Sanders scores upset in Michigan; Clinton takes Mississippi, while Cruz picks up win in Idaho

Bernie Sanders pulled off a shocking upset in Michigan's Democratic primary Tuesday night, beating Hillary Clinton in a race that some polls had him trailing by double digits and eclipsing the front runner's earlier win in Mississippi.

Republican front-runner Donald Trump, meanwhile, regained any momentum lost last weekend against challenger Ted Cruz, sweeping to convincing victories in Michigan and Mississippi while sending a message to the Republican establishment to jump on board — or get out of the way.

Cruz was projected to pick up a win in the Idaho GOP primary, while Trump was projected to easily win the Hawaii Republican caucus.

But Trump's earlier victories were more valuable in terms of delegates. And Tuesday's results may also seal the fate of Marco Rubio, who appeared once again to finish the night failing to gain any delegates.
