(CNN) The 2020 Democratic field is rounding the first major marker of viability in the race: Fundraising over the first three months of 2019. Presidential fundraising is not simply about who can court more rich people to write them a check. Joe BidenOne of the main reasons Biden didn't enter the race in March was that he didn't want his first quarter fundraising totals compared to people like Sens. If he enters the race, he'll have between then and June 30, the end of the second fundraising quarter, to prove those doubters wrong. Which is $15 million more than I have ever raised, but is nowhere near the past fundraising totals of Warren ($40+ million raised in 2016) and O'Rourke ($80 million raised in 2018).
