You are amazingly partisan and dishonest.
1: “The second reason is that the non-gerrymandered Senate remains less polarized than the House — at the moment, for instance, they’re easily passing legislation to reopen the government.”
False. The House has passed 20 bills to fund part or all of the government, almost all of them on a bipartisan basis. The Senate has approved of 2 of them, and is holding up the rest. The “hostage takers” are in the Senate, on your side.
2: “Though both parties have moved toward their respective poles, Republicans have moved much further right than Democrats have moved left.”
How many Democrats in the Senate opposed ObamaCare? 0. How many of them had constituents who supported ObamaCare?
It’s votes that count. And when the vote is on the line, it’s the left that owns the Democrat Party.
3: “Because for most of American history senators used the filibuster extremely judiciously. That’s all changed in recent years. The Senate had to spend more time breaking filibusters in 2009 and 2010 than in the 1950s, 1960s, and 1970s combined.”
Gosh, WHEN did that change? When did a minority decide that they didn’t care about the election results, they wanted their way, and that’s all that mattered? Would that be in 2003, when the Democrats lost their majority?
