Kentucky Representative Thomas Massie faces a decisive primary challenge on Tuesday that serves as a critical litmus test for the influence of President Donald Trump within the Republican Party.Massie is defending his seat in the 4th Congressional District against Ed Gallrein, a former Navy SEAL who received an emphatic endorsement from the President during this record-breaking campaign.The race has been marked by millions of dollars in spending from groups like AIPAC, following Massie's consistent opposition to foreign aid for Ukraine and Israel while advocating for domestic fiscal discipline.Polling expert
Patrick Allocco notes that the endorsement from Trump has shifted momentum toward Gallrein, underscoring deep ideological fractures within the
GOP ahead of the upcoming midterm elections.
