For the last decade or so, Republicans have voted in Representatives and Senators on the sole basis that they were going to be obstructionists, say no to pretty much everything and never ever work with anyone across the aisle to get anything done; and now they are surprised that those same people don't have a clue on how to get legislation passed.  Who's really at fault here?

P.S. Anyone that thinks that Trump gets a B+ at this point (almost 1000 tweets, 41 trips to a Trump golf property, fired or resigned - FBI Director, U.S. Attorney for NY, Nat. Security Advisor and the WH Press Secretary {to name a few} and ZERO pieces of legislation passed) is either an idiot or isn't paying attention.
