Hillary Clinton is a liberal Democrat. Look at her voting record. And don't cherry pick the times she sided with the GOP. Look at her voting record as a whole. It's liberal, and 93% in alignment with Bernie Sanders.PATRIOT Act? Bipartisan. War in Iraq? Bipartisan. NDAA? Bipartisan, and strongly supported by Barack Obama, who was a constitutional lawyer in his past life. Democrats and Republicans alike are in love with the TPPA, and the Democrats are just as much to blame as the Republicans for the fact that we still don't have single-payer. There are a few isolated issues where the Democrats are in line with real liberal values, but they are few and far between. When it comes to most of the issues that matter, Democrats are just as happy to stick to the status quo as the Republicans. They also made sure that Hillary Clinton, who has a long history of being a "Third Way" Democrat (which is code for being a Republican with a "D" behind her name), beat Bernie Sanders in the primary. The Democratic Party is not fighting for ordinary citizens.
You decided to cherry pick the times the Democrats sided with the GOP on certain conservative issues, but as whole, the Democrats is a much more friendly party for regular citizens.
In addition, I'd like a Democrat who knows how things work. Centrist Democrats aren't opposed to universal healthcare, they just want to find realistic ways to achieve that, and Bernie's plans are simply not plausible. He wants Medicare for All, and yet tries to cut Medicare spending at the same time. That is simply not possible. We have to spend more on Medicare if we want Medicare for all. Bernie is able to unite progressives and get them to support causes, but as for the actual policymaking and bills... leave that up to the people who actually have realistic solutions, like Durbin or Bennet.
Yes, the Patriot Act, War In Iraq, and NDAA were all passed with bipartisan support, but there has also been plenty of times the Dems decided to side with the people. I only listed 4 times because there were so many, and I wanted to stick with the highlights, but if you're still not convinced both parties aren't the same, I can list 20 more times the Dems sided with the people.
The fact is that while both parties may be bad for the US, one is definitely worse, and that's the GOP. Furthermore, political parties will always exist in the US. Political parties aren't the problem in the US. If we got rid of political parties, there'd still be plenty of partisanship. If we take a look at Nebraska, they have a "nonpartisan" state legislature where people are supposed to affiliate with no parties. But do they? Although the state legislature members are "nonpartisan" by law, they are de facto part of a party. The like minded members will form factions, which turn into voting blocs, which will turn into parties, whether the government recognizes the parties or not. You can hate on political parties all you like, but they will always exist, as like minded people will want to work with each other on issues.
