Former Vice President Joe Biden's first events of his presidential campaign drew a wave of attention this week, prompting other candidates to answer questions about how they would contend with the man who has led nearly every national poll this year. But before the field takes aim at Biden, they must first compete among themselves for a spot in the first two Democratic debates.
Colorado Sen. Michael Bennet's entry into the race Thursday lifted the field to 21 major entrants, eclipsing the Democratic National Committee's 20 participant limit for the two nights of debates. Now, the candidates have mere weeks to drive up their numbers of individual donors and attempt to climb the polls so as not to be the lone person left off the stage and out of the conversation.

Abrams announced Tuesday that she would not seek the Democratic nomination in Georgia's 2020 Senate election, prompting increased speculation that she could mount a presidential bid, particularly after she said in a radio interview that day that she "keeps giving thoughts to other opportunities."
In the video in which she made her Senate announcement, Abrams, who unsuccessfully ran for Georgia governor in 2018, said, "the fights to be waged require a deep commitment to the job and I do not see the U.S. Senate as the best role for me in this battle for our nation's future."
Bennet formally announced the launch of his presidential campaign in an interview with "CBS This Morning" on Thursday, becoming the 21st Democrat to enter the race and pitching himself as someone who could work across the aisle.
"I've got a track record of bipartisan work that's been harder to do during the Trump administration," he said in the interview.
The Colorado senator -- a former superintendent of Denver Public Schools and chief of staff to then-Denver Mayor John Hickenlooper, now a fellow Democratic presidential candidate -- also released a video outlining some of his positions, including a public health care option.

After entering the presidential race last week, Biden appeared on ABC's "The View," was interviewed with his wife, Dr. Jill Biden, by ABC's Robin Roberts, co-anchor of "Good Morning America," and then held his first campaign event Monday in Pittsburgh, before continuing on to Iowa for a two-day tour of the Hawkeye State.
In Pittsburgh, Biden courted union voters and earned the endorsement of the International Association of Fire Fighters, a decision met with derision by President Donald Trump, who launched a tweetstorm Wednesday in the wake of the announcement.
During the interview that aired on "Good Morning America" Tuesday, the Bidens addressed issues from the former vice president's past that have drawn criticism, including the treatment of Anita Hill during Supreme Court Justice Clarence Thomas' 1991 confirmation hearing before the Senate Judiciary Committee in which Biden said she wasn't "treated well."
"I apologize again because, look, here's the deal. She just did not get treated fair across the board. The system did not work," he added.

The South Bend, Indiana mayor and his husband Chasten are featured on the cover of Time Magazine this week, and the pair's relationship and Buttigieg's recent rise in the presidential field are featured in a profile.
Buttigieg calls himself a "policy guy" in the story, elaborating, "Every good policy that I've developed in my administration happened not because I cooked it up on the campaign, kept the promise intact and then delivered it, but because I stated a priority in one of my campaigns, interacted with my legislative body and my community, and developed something that really served people well."
Chasten Buttigieg was the focus of his own Washington Post profile, in which his coming-out story, bout with homelessness and popularity on Twitter were detailed.

Gabbard's focus on foreign policy continued this week, including in a Fox News interview in which she expressed concern over how the conflict in Venezuela would affect the U.S. and Russia.

After Harris' questioning of Barr during Wednesday's Senate Judiciary Committee hearing, the California senator was singled out by Trump who said she was "probably very nasty" to the attorney general, during an interview with the Fox Business Network.
Harris joined with several other Democratic candidates in calling for Barr's resignation, saying in an MSNBC interview that he was aware he was misleading the public and tweeting that his responses to her questions at the hearing -- including his acknowledgement that he did not review all of the special counsel's underlying evidence prior to writing his summary of the Mueller report -- were "unacceptable."
Former Colorado Gov. John Hickenlooper released a five-page outline for his "New Open and Fair Trade Policy." His plan, according to CBS News, calls for greater trade cooperation and includes adding climate change goals into trade agreements.
Hickenlooper also welcomed Bennet, who served as an adviser to Hickenlooper's campaign for Denver mayor and later as his chief of staff for two years, into the 2020 presidential race in a tweet saying, "Welcome to the adventure of a lifetime @MichaelBennet! Good luck on the campaign trail."

You look at the totality of the evidence and the pattern here," Klobuchar told Barr after the Attorney General attempted to explain why he concluded that Trump's actions related to the Mueller probe did not amount to obstruction of justice.
In an interview with Reuters, Rep. Seth Moulton, D-Mass., criticized his fellow 2020 presidential candidates Sens. Bernie Sanders and Elizabeth Warren for pushing America "too far left," and for being just as "divisive" as Trump.
