Hiram Alejandro Durán/THE CITY When Sheila Lewandowski moved to Long Island City in the late 1990s, she appreciated the “sense of space and light” in the western Queens neighborhood, once defined by factories, warehouses, and a mix of blue collar workers and creative types like herself. Now, high-rise buildings erected over the last decade have cast shadows on everything beneath them — and the explosive growth of neighborhood residents is also remaking the political map. Her City Council district, where 20 candidates vie to succeed term-limited Jimmy Van Bramer, has seen voter registration soar, with 22% more Democrats and 18% more total voters eligible to vote in this June’s primary than the last citywide Council election in 2017.
