Below the Michigan average

Michigan's two Democratic senators sit apart on this measure, and Peters is the lower of them.

Among the 2 Democrats in the Michigan delegation, the average rate of voting against the party majority is 5.2%. Gary Peters is below that average at 4.1%.

What he legislates on

No single subject dominates the classification. The bills cover safety of human cell and tissue products, housing financial literacy, tribal conservation priorities, an allowance for introducing noncompliant vehicle equipment into commerce for testing, and expanded whistleblower protections for contractors. Several are the kind of narrow administrative fix that rarely attracts attention and quietly matters.

Sponsored bills carry the Congressional Research Service's own subject classification. Gary Peters's cluster into: Crime and Law Enforcement (1), Environmental Protection (1), Finance and Financial Sector (1), Foreign Trade and International Finance (1), Government Operations and Politics (1), Health (1).

Tenure and attendance

The tenure count runs from a House seat won late in the two-thousands, not from his arrival in this chamber. He misses a small share of votes.

First elected in 2009, now serving across 9 terms. Gary Peters falls in the veteran cohort.
