Levy, Jonah. The state after statism: new state activities in the age of liberalization. Florence: Harvard University Press. 2006: 198.ISBN 0-495-50112-3.In the corporate governance area, thecenter-left repositioned itself to press for reform. The Democratic Party in the United States used the postbubble scandals and the collapse of share prices to attack the Republican Party ... Corporate governance reform fit surprisingly well within the contours of the center-left ideology. The Democratic Party and the SPD have both been committed to the development of the regulatory state as a counterweight to managerial authority, corporate power, and market failure.
Zurcher, Anthony.US election: How left-wing is the Democratic field?. BBC News. 2020-02-24 [2021-12-14].The party has moved rather decisively to the left on trade in recent years, however, with Elizabeth Warren opposing the Trans-Pacific Partnership, among other recent trade deals. Bernie Sanders has gone one step further, opposing Trump's Nafta renegotiation, the US-Mexico-Canada agreement.
America’s Democrats are losing their moderates.The Economist. 2021-10-29 [2021-12-14].Bill Clinton’s and Barack Obama’s presidencies were in part a victory for prudent activists who argued that appealing to the centre-left could outweigh the votes from the Republicans’ conservative base. But now the Democratic Party may have shifted too far to the left. New research from YouGov, a polling firm, suggests that despite its recent wins the party’s popularity is decreasing—especially among moderates.
此外就您给出的几点理由：
爱国主义：2. How partisans view each other.Pew Research Center. 2019-10-10 [2021-12-14].Republicans are substantially more likely to characterize Democrats as more unpatriotic than other Americans than Democrats are to say this of Republicans: 63% of Republicans view Democrats as more unpatriotic.
您所举的例子：“The Democratic Party and the SPD have both been committed to the development of the regulatory state as a counterweight to managerial authority, corporate power, and market failure.”，社会民主党的政策普遍执行力比民主党高得多，以及支持和平主义、裁军等，总体比民主党左，而民主党的偏左政策普遍还停留在纸面上。

我找到的来源基本是五五开的，要么强调民主党是一个中左到中间的政党（如上所列），要么隐晦的不提及民主党的具体立场（虽然在我看来这些来源可能认为偏中间），但是反复强调民主党的左翼/进步力量正在崛起。还有，您所说的左翼自由主义是指自由意志社会主义吗？毕竟我找到的现代自由主义的来源基本要么说其是左翼（Beauchamp, Zack.Identity politics isn’t hurting liberalism. It’s saving it.. Vox. 2020-02-20 [2021-12-17]（英语）.These critics accuse identity politics of being a cancer on the very idea of liberalism, pulling the mainstream American left away from a politics of equal citizenship and shared civic responsibility.）、要么说其是中左翼（Center-Left Liberalism.），也符合“左翼自由主义”这个定义。
“In Congress, the party is a big-tent coalition with influential centrist, progressive, and conservative wings.”[1]
“Political scientists characterize the Democratic Party as less ideologically cohesive than the Republican Party due to the broader diversity of coalitions than compose the Democratic Party.”[2][3][4]
“In Congress, the party is a big-tent coalition with influential centrist, progressive, and conservative wings.”
“Political scientists characterize the Democratic Party as less ideologically cohesive than the Republican Party due to the broader diversity of coalitions than compose the Democratic Party.”
“A conservative Democrat is a member of the Democratic Party with conservative political views, or with views relatively conservative with respect to those of the national party. While such members of the Democratic Party can be found throughout the nation, actual elected officials are disproportionately found within the Southern states and to a lesser extent within rural regions of the United States generally, more commonly in the West. ”[5]
“In Congress, the party is a big-tent coalition with influential centrist, progressive, and conservative wings.”，说实话这个我也是刚看见的，因此我现在有点想把这个讨论推到客栈了（顺便带上共和党，因为英维共和党也差不多是这么处理的），但是我觉得最后结果可能也就是“不按着英维而按着找到的主流来源写成‘中间和中间偏左’”。
意识形态里的“左翼民粹主义”和“民主社会主义”很显然是左翼政治立场。左翼的国会进步小组（Congressional Progressive Caucus）在众议院拥有99个席位，而中间派的蓝狗联盟（Blue Dog Coalition）仅拥有19个席位，且当前的蓝狗联盟实际上随党内主流左倾化了，也被认为是中间偏左的派别。这样一来民主党政治立场一栏的“中间偏右”就是不成立的（或者说只有两名议员可能符合中间偏右标准），中间派也只是派系之一，主流是中间偏左。--西安兵马俑主义好！🇺🇸🇨🇭🇱🇮🔞创建的条目2022年8月20日 (六) 10:29 (UTC)回复
西班牙语维基也对民主党的政治立场有问题，可以见他们的讨论，有不少认为民主党属右派的。但再怎样还是民主党内的（New Democrats）派占主导位置（民主党高层都是这个派别的），政治立场属于中间，其他派别都是从属地位（引用英维：“New Democrats dominated the party from the late 1980s through the mid-2010s”）。--lenin1917（留言）2022年8月21日 (日) 08:29 (UTC)回复
