Results run through the 2024 elections; nothing from 2026 is shown until it is certified. A margin is a fact about one election, never a score of how well a member represents anyone, and PORKER does not rank members by it.
How has Colorado’s 4th district done while Rep. Musgrave served?
2005 to 2008 in CO-4: typical household income was up 5% after inflation, the share of people below the poverty line was about the same, and the share of workers looking for a job was down 1.4 points.
Each mini chart has its own scale, fitted to its lines (it does not start at zero), so compare the numbers, not the heights. Teal = district, oxblood = state, grey = U.S.
While they served, not because of them. This shows what happened in Colorado’s 4th district during Musgrave’s time representing it (2003 to 2009). It does not say what the member did or caused. It is not a score, and PORKER never ranks members on it.
One set of district lines. CO-4 was redrawn in 2012 and again in 2022 (the survey year the new lines first appear), but every survey year in Musgrave’s term so far (2005 to 2008) uses the same lines, so they can be compared. The Census Bureau has no 2020 yearly estimate.

Read this first. These are counts of records Congress.gov lists. Many bills never get a CBO estimate or a report, so a zero is not a mark against a member. We never show this as a score.
