Who has stopped more bills in the Congress--harry Reid or Mitch mc Cornell?

Harry Reid, as the former Senate Majority Leader from 2007 to 2015, and Mitch McConnell, who has served in the same role from 2015 to 2021 and then as Minority Leader, both played significant roles in halting legislation. However, McConnell is often noted for his strategic use of filibusters and other tactics to block bills, especially during a divided government. The comparison largely depends on the specific time frames and political contexts being analyzed, but McConnell's tenure has been marked by a notable increase in partisan gridlock. Overall, both leaders have significantly shaped the legislative landscape, but McConnell's approach has been more publicly characterized by obstruction.
