Until Nayor Bill de Blasio and his Chancellor, Richard Carranza, pushed to eliminate the SHSAT by claiming it was a "racist" test and anybody supporting it was "racist", the East Asian community was non-0political and accommodating. The blowback to the Mayor and Chancellor was immediate and severe. The Chinese-American community rose up and called their politicians and the Mayor's plan was never voted on in Albany.
The Mayor and Chancellor tried to get their allies to support his plan to eliminate the SHSAT and allow every middle school student who was in the top 5% to be automatically enrolled in the specialized high schools. The problem was they deliberately excluded the East Asian community and it was so blatant that even many of the Mayor's allies saw the exclusion of the East Asian community as discrimination.
The Mayor's and Chancellor's ill-advised attempt to eliminate the SHSAT gave rise to a politically conservative Chinese-American group that has become politically savvy and media sensitive that resulted in the City's plan to eliminate the SHSAT to become dead on arrival when it showed up at the Democrat controlled State Senate.
Many of the Serrate Democrats were recently elected in previously moderate Republican districts and are not allies of the progressive Mayor Bill de Blasio and don't want to be associated with him when they try to get reelected in their districts. The Mayor's integration plan, while not directly affecting their communities still will have negative consequences by giving their Republican challenger a talking point that they are a "rubber stamp" for the Mayor.
Obviously, the Governor is no fan of the Mayor and with the Senate Democrats shifting toward the middle of the political spectrum as reelection nears, he Mayor's plan to eliminate the SHSAT looks to be a goner in Albany.
