Is Elizabeth Warren the left’s Ted Cruz?

But one key distinction is how far they are willing to push their opposition efforts. Another is how they are viewed by party leaders.

While Cruz launched a marathon anti-Obamacare filibuster on the Senate floor in 2013 and built enough support for his cause to actually shut down the government temporarily, there is no evidence yet that Warren is willing to go quite that far.

Asked repeatedly during a press conference Wednesday whether she would block the funding bill on the Senate floor, Warren repeatedly sidestepped the questions, insisting that her pressure was aimed squarely at the lower chamber to ensure the bill doesn’t ever make it to the Senate in its current form.
