The LTE laments that Trump, Schumer and Pelosi are not up to their leadership responsibilities.
Pelosi has gotten bills ready to pass on to the Senate for a myriad of issues including voting rights, gerrymandering, stabilizing ACA and the like. She has also sent the bill for opening the government. She has managed to secure the Speaker of the House despite a lot of rumbling from the freshman and fringe representatives.
Schumer is doing what he can as Minority Leader, which in the Senate is kind of limited.
Trump and McConnell, however, have abrogated their responsibilities in the name of securing a core of voters that represent at best about 20% of the population. McConnell is particularly deplorable since he has the power to open the government by passing the bill to do so thus forcing a veto if such be the case. We have not even seen his face since the first of the year.
The Oval Office and the Senate are where the leadership vacuum lies.
Pure and simple.
