The For the People Act of 2021 passed the House as HR 1 with no Republican votes. On March 17 it was introduced to the Senate as S.1 by Senator Markley and 48 Co-Sponsors. It was notable that that all were Democrats or Independents.
Republican also united in the Senate Rules Committee to oppose the bill.
Is there any specific part of the bill they do not like or is it just generally opposition to fair elections?
