Who will be the next president?

In announcing his candidacy for president Wednesday, Vermont Sen. Bernie Sanders, an independent, said, “People should not underestimate me. I’ve run outside of the two-party system, defeating Democrats and Republicans, taking on big-money candidates and, you know, I think the message that has resonated in Vermont is a message that can resonate all over this country.”

Sanders is the first major challenger to enter the race against Hilary Clinton, who earlier this month became the first Democrat to formally declare her intention to run for president. He is likely to be joined in the coming months by former Maryland Gov. Martin O’Malley, former Virginia Sen. Jim Webb and ex-Rhode Island Gov. Lincoln Chafee.

Announced Republican candidates include U.S. senators Ted Cruz, Marco Rubio and Rand Paul. Likely GOP contenders include former Florida Gov. Jeb Bush and Wisconsin Gov. Scott Walker.
