The right and honest brokers on the left agree that vote by mail by itself is a flawed voting system.  It has problems with voter error, delivery issues, chain of custody, fraud and more.  In-person voting is the best option for most voters (though some additional absentee voting may be needed to respond to the unique challenges presented by the COVID-19 pandemic). 

However, we never expected to see support for in-person voting over vote by mail come from liberal stalwart Alexandria Ocasio-Cortez:

It is completely wrong for the BOE to cancel New York’s Presidential Primary.

This decision is not informed by public health: the state is still holding elections for every other seat that day, & so far the only way your ballot will 100% be counted in NY is to vote in person! https://t.co/l8iT7mxm9c

Now that Republicans have lost their longstanding majority in the New York Senate, New York rushed through several election "reforms" at the beginning of the legislative session, with no committee hearing process or input from the public.  The package of legislation* was introduced on January 10, passed the Assembly and Senate on January 14, and was signed by the Governor on January 24.  This likely foreshadows how the Democrats will rush House Resolution 1 through the House on the federal level, though fortunately, the Republican majority in the Senate under the leadership of Majority Leader Mitch McConnell will block its harmful provisions from becoming law on the federal level.
