Yeah, seems to me the problem isn't the Democratic Party's position relative to the rest of the world, but rather the combined factors that the Republican Party is extremely far-right relative to the rest of the world, and also systemic bias that enables regressive/stagnant policy. (lol that basically just summed up what you said, oh well)
Think of it this way - Obama's party won the popular vote in 2012. Due to gerrymandering, they were unable to win the House majority despite this. Had they done so, they could have at the very least enacted
comprehensive immigration reform and
ENDA (nondiscrimination against LGBT people in the workplace, which the Supreme Court basically enacted last month - noteworthy that the Dem party platform has basically upgraded this position to the Equality Act which covers a much broader spectrum of issues), as these are both things that passed the Senate majority with token Republican support and would have passed even the barest House majorities. However, Obama also floated a number of other policies for his second term that were never given the chance due to this and that reason - the
American Jobs Act (extra stimulus) and
comprehensive background checks for gun purchases/assault weapons ban both failed to beat filibusters. Abolishing that alongside controlling the House would have allowed all of those bills to pass, alongside
a public option for healthcare,
free community college, universal pre-K and
an increase in the minimum wage, all of which were things Obama proposed and re-proposed throughout his second term, and things we still don't have.
Poll after poll suggested these proposals had popular support as well, but gerrymandering, disproportionate Senate control/the filibuster, and finally the Electoral College bias made all of this impossible. Additionally, our state governments being gerrymandered also made it impossible to implement any of this stuff meaningfully at the state level (outside of a handful of safe blue havens), while also compromising things like the Medicaid expansion which Democrats DID achieve but required cooperation from the states.
All this to say, we've had about a lost decade or so of progressive policy gain and ignorance/naivete has led people to assume "the Democrats don't want to do anything" rather than acknowledging the systemic issues and problems inherent in the Republican Party that have kneecapped our ability to capably govern.
