Following their assumption of a Democratic majority in Congress, the party is poised for a significant shift toward the left, particularly influencing the upcoming 2028 presidential primary, according to Ari Fleischer in an opinion piece for Fox News.

Fleischer anticipates a surge of Democratic presidential candidates, potentially exceeding the 29 who declared in 2019-2020. This shift is seen as a response to the Republican Party's transformation under Donald Trump, with progressive and redistributive socialist factions gaining influence within the Democratic Party.

While legislative achievements might be limited due to the president's veto power, Fleischer argues that the primary goal for Democrats will be to advance progressive agendas. Policies such as Medicare for All, abolition of ICE, and cutting support for Israel are expected to become Democratic priorities, even if they face vetoes. The elimination of the filibuster is also anticipated, potentially paving the way for measures like an expansion of the Supreme Court or statehood for certain Democratic strongholds, alongside nationwide taxes on billionaires and millionaires. These efforts, though likely to be vetoed, are viewed as strategic moves to set the stage for future legislative successes, drawing parallels to past instances where long-standing policy ideas eventually gained traction.

Fleischer suggests that this leftward trajectory will create a strong alignment between progressive members of Congress and presidential candidates, as candidates seek to define themselves for primary voters by advocating for these policies. He posits that this movement will marginalize moderate voices within the party, akin to how Donald Trump's rise shifted the Republican Party.

The author concludes that this embrace of more progressive policies by Democrats, while energizing the party's base, could ultimately make it more challenging to win the presidency in 2028. Nevertheless, he characterizes this leftward momentum as an unstoppable force, stating, "The Democrats’ significant majorities won’t shield them from the energy the left has on the party. Democrats run as moderates, but then govern from the left." The push to advance these policies, even if unsuccessful in the short term, is seen as a deliberate strategy to shape the party's future direction and presidential contenders.
