evidence: Wall Street and finance executives placed their early 2020 bets on a variety of Democratic presidential candidates, from Pete Buttigieg to Kamala Harris, even as the contenders try to distance themselves from big-money donors. [...] The early fundraising totals, which were disclosed on Monday in Federal Election Commission filings, show that some players in the financial industry are interested in backing certain candidates early on, including Sens. Cory Booker and Kirsten Gillibrand and former Texas Rep. Beto O'Rourke. [...] Buttigieg, the South Bend, Indiana, mayor, raised just over $7 million in the first quarter. According to filings, $5,600 came from Stephen Schuler, a director at Chicago-based investment firm Wicklow Capital. During the 2018 congressional midterm elections, Schuler spent well over $1 million in support of Democrats, records show. Employees at Wicklow Capital combined to give at least $11,200 to Buttigieg throughout the most recent quarter. He has publicly sworn off support from corporate PACs and contributions from the fossil fuel industry.
