The Rapid Decline of Moderate Republicanism

The Institute for Legislative Analysis (ILA) has released an ideological index showing a dramatic consolidation within the Republican Party during the first year of President Trump’s second term. According to the report, the number of Republicans maintaining a moderate voting record has dropped elevenfold in just three years, falling from 33 members in 2023 to only three in 2025. This shift reflects a tightening of the party's ideological core as lawmakers increasingly gravitate toward a unified policy agenda centered on reduced federal spending and restricted regulatory power.

Democratic Course-Correction and Internal Variation

While Republicans have consolidated, the Democratic Party is beginning to show signs of philosophical fracturing. The ILA found that the number of Democrats scoring above 10% on their limited-government scale rose from 28 in 2023 to 99 in 2025. This "modest" shift away from the left is largely attributed to members from swing districts responding to voter concerns regarding border security, crime, and national defense. Despite this movement, the report notes that Democrats remain more unified overall than their Republican counterparts, with an average ideological score of 10.31 compared to 79.62 for the GOP.

A Pivot Toward Populism and Nationalists Policies

The report highlights a significant departure from traditional Republican orthodoxy, which historically prioritized free trade and constitutional civil-libertarian instincts. The current GOP voting patterns reflect a more populist governing style that has normalized the use of tariffs and expanded state power in specific industrial sectors. This transition is exemplified by the voting trajectory of Senator Josh Hawley, whose score dropped from 84% to 70%, signaling a movement toward a "nationalist" policy preference where trade and state intervention intersect.
