A new Supreme Court campaign finance ruling has sparked criticism from lawmakers across the political spectrum, with opponents warning it could increase party control, expand billionaire influence and weaken voter representation in U.S. elections.

Massie, Sanders And Others Slam Supreme Court Ruling On Tuesday, in a post on X, Sen.

Thomas Massie (R-Ky.) said the ruling would shift influence away from voters and toward party leadership.

"The net effect of this decision is political parties will have more power over individual candidates," he wrote.

He added that elected officials would feel greater pressure after winning office, saying they would be "more obligated to vote with their parties instead of their constituents." Massie also warned about the impact on independent lawmakers, stating, "Fewer Thomas Massies and Ro Khannas, more zombies." The net effect of this decision is political parties will have more power over individual candidates.
