But the party establishment is so horrifically bad at reading its voters that it keeps putting up corporatist dDems in the mould of Ray-Gun or Shrub*, hence why Platner got so much traction despite having so many red flags. He was willing to talk the talk that ordinary Democratic party voters need to hear.
You're objecting to the kind ofe economic and social policies that millions of drowning Americans need if they are ever going to survive.
*i.e. a hairs-breadth to the left of current GOP policy, but circumspect enough not to shout it from the rooftops.
Jesus christ on a cracker, the whole "moderate/centrist Democrats are almost identical to republicans" is such an idiotic argument.
Lets look at (for example) Biden (someone who is seen as a fairly moderate democrat) and compare him to the current iteration of the GOP....
Biden increased funding for green energy programs. GOP cut green energy programs and are pushing fossil fuels.
Biden appointed a judge to the bench who voted to keep roe v. wade, Trump's judges all voted against roe v. wade.
Biden proposed a tax increase on high income earners and corporations. Republicans cut corporate taxes.
Biden attempted to provide limited student loan debt relief. Republicans nuked it.
Biden expanded the number of people covered under Obamacare. Under Trump the number of people covered has been dropping, and medicare has been severely cut.
Notice the significant differences between the parties? Things would have been radically different had a republican been in charge instead of Biden.
Ok, Biden's expansion of Obamacare wasn't exactly the "medicare for all/single payer" that progressives want, and his student loan debt relief wasn't the "free college" that the far left wants, but they are noting like the republican plans for health care or education.
Now, there may be legitimate discussions on how fast the democrats should go in pushing left-wing policies, but anyone suggesting "Moderate Democrats are almost like republicans" makes a person sound less like a rational person who wants a reasonable discussion on policy, and more like and edgy teen who got their political views from a North Korean youtube video that was translated by Russian bots, and they are saying things just to piss of their parents.
Oh, and by the way, Moderate democrats in the form of Clinton, Biden, and to a lesser extent Obama have won elections. In fact, going back to the mid-90s, there has only been 1 election (Bush in 2004) where the republicans have actually won a clear victory (winning both in the popular vote AND in the electoral college). In every other election, either Democrats outright won (e.g. Biden over Trump), Won the popular vote but lost the electoral college (e.g. Trump vs. Clinton, Bush vs. Gore), or at the very least kept the republican from getting a majority (Trump vs. Harris). Its only because republicans appeal to people in states with more cows than people that they have maintained any power. That's pretty good for a bunch of people who you claim "don't know how to read voters".
