@compforce I think that's a misrepresentation of the Obama presidency - especially during the first 3 years. Much of the tumult over the ACA was due to President Obama's efforts to include Republican votes. Though I agree the later portion of his first term and second devolved to almost total gridlock. I think political scientists and historians will credit the Obama administration with a great deal of outreach across the aisle - but also fault it for the lack of success. I read somewhere that no party has controlled all 3 branches of government (including the judicial) since the 1920s - but I take your point on executive and legislative.
My larger point was that the pressure to reach across the aisle to legislate has largely dissolved over the last 15 years for a variety of structural reasons - and that's bad for democracy. Both parties have to pursue an electoral strategy towards turning out reliable voters (and suppressing the other party's voters) vs trying to convince 'swing' or 'undecided' voters to move over. It means there's very little room to compromise legislatively because of ideological pressure - even where the policy positions line up pretty well.
That's why I disagree with
@Blizzard as well on the importance of the popular vote. Wherever the final tally lies - and I've read it could be anywhere from .5 - 2 million against the PE - it displays a profound split in the politics of the country. It seems structurally unsound to me to govern in a 'winner take all' manner when half your populace (or at least the ones that bothered to vote) disagree with your positions. That should generate a desire to compromise or move to the middle in at least some areas. But, I think looking at the electoral map with such a powerful demographic divide, rural/city divide, gerrymandered districts, dark money, tailored media, and the loss of earmarks it seems to me the institutional set-up pushes against that kind of governance.
I was reading an article that said what makes democracy strong is not it's efficiency or ability to get the right answer on policy - but it's ability to withstand internal pressure. A democracy has the ability to peacefully transition power at multiple levels and ensures factions do not have to resort to violence to ensure their survival. Its the ability to protect the minority that makes the majority stronger.
