Only transparency will push back the notion that the Senate should be abolished. The publication of attendance is refreshing move. Many neocons demanded the abolishment even when Stevie's own appointees miscued. Let's have their expense budgets/spendings also published. 
Many senators participate in the review and amendment of legislation. Constitutional practice today basically means that the Senate will delay measures the majority oppose but will not veto it. A' sober second house' is critical in this age when politicians reaping rewards from an angry electorate. Opposing a trumplike demagogue's whims is their role. 

Appoint senators with expertise that will benefit their role.

Keep the Senate and  continue to make them transparent.
