As the number of Democrats running for president grows, the 2020 hopefuls fanned out across several early-voting states over the weekend and met with voters in some of the states that will have an early say in determining the nominee. Sens. Cory Booker of New Jersey and Sherrod Brown of Ohio were in South Carolina, site of the South’s first primary, drawing diverse audiences in the state where the primary electorate is largely composed of minority voters.

Sen. Bernie Sanders of Vermont made Brooklyn the official launch site of his second run for the White House, saying his campaign is tailor-made to defeat President Donald Trump. In Iowa, Sen. Elizabeth Warren of Massachusetts courted voters. Sen. Amy Klobuchar of Minnesota was scheduled to attend the Gridiron Club dinner in Washington, an event where politicians traditionally poke fun at the press and other politicians.

Trump spoke to a gathering of conservatives in suburban Maryland, where he mocked Democrats for their framework to combat climate change and said House lawmakers pushing to expand their investigations of him are “sick.”

Sanders will hold a rally in Council Bluffs 6:30-p.m. Thursday, March 7th, in the Exhibition Hall at the Mid-America Center, 1 Arena Way. The event is free and open to the public. Tickets are not required, but an RSVP is encouraged. Entrance is provided on a first come, first served basis. The Iowa City event will be co-sponsored by University of Iowa Democrats and the local chapter of Young Democratic Socialists of America. Similar rallies are planned for Iowa City and Des Moines later next week.

Calling Trump the most dangerous president in modern U.S. history, the Vermont senator said that his campaign is built to defeat Trump. Sanders pledged to fight for “economic justice, social justice, racial justice and environmental justice.”
