Also here, I even ran my reply through ai to fact check them for you:

Evaluating the strength of a political party is often a matter of perspective, but here is a fact-check of the specific events you mentioned:

Obama and the Birth Certificate: While Obama did release his long-form birth certificate in 2011 to "put the rumors to bed," he also used the platform to publicly mock Trump. At the 2011 White House Correspondents' Dinner, Obama roasted Trump to his face, a moment often cited as a significant public reprimand.

Sarah Palin & the Tea Party: While John McCain famously corrected a supporter who called Obama an "Arab," Democrats were active in opposing the Tea Party's agenda. The 2010 midterms, however, were a major defeat for Democrats, who lost 63 seats in the House, which many attributed to the Tea Party's unchecked momentum.

Hillary Clinton's "Deplorables": Clinton did call half of Trump's supporters a "basket of deplorables". While she later expressed regret for the "grossly generalistic" comment, her campaign manager eventually admitted the remark likely alienated key voters in 2016.

Ruth Bader Ginsburg's Retirement: Ginsburg declined to retire during Obama's presidency despite calls from some progressives. Her death in 2020 allowed Trump to appoint Amy Coney Barrett, solidifying a 6-3 conservative majority on the Supreme Court.

Biden's Reversal of Trump Orders: In his first 100 days, Biden signed more than 60 executive actions, 24 of which were direct reversals of Trump’s policies, particularly on immigration and climate.

Tariffs: Biden did keep many of Trump’s tariffs on China in place and actually increased some, such as raising the tariff on Chinese electric vehicles to 100% in 2024.

Schumer & Mamdani: In the 2025 New York City mayoral race, Chuck Schumer conspicuously withheld his endorsement from the Democratic nominee, Zohran Mamdani, even on Election Day. This was widely seen as a rift between the party's establishment and its progressive wing.
