Mike Crapo has represented Idaho in the U.S. Senate since 1999. He’s one of the chamber’s most entrenched voices on tax policy, banking regulation, and fiscal restraint — the guy who actually reads the pay-for tables in the Finance Committee markup.
Crapo pushes lower taxes, deregulation, and aggressive deficit reduction as the formula for growth. He’s also a reliable vote for gun rights and domestic energy development, and a sharp critic of what he calls federal overreach in environmental regulation.
Seen as a steady, establishment-aligned conservative, he usually works within party leadership and industry circles, which wins him influence on economic legislation — and heat from critics who say he’s too close to corporate power.
