The Cook Political Report with Amy Walter is an American online newsletter that analyzes elections and campaigns for the U.S. Presidency, the United States Senate, the United States House of Representatives, and U.S. governors' offices. Self-described as independent and nonpartisan, it was founded by political analyst Charlie Cook in 1984. Amy Walter is the editor, publisher, and owner. The Cook Political Report with Amy Walter was previously a hard-copy publication known as The Cook Political Report. The Report moved to an all-online format in 2004. On July 30, 2021, the publication name changed to "The Cook Political Report with Amy Walter," as Walter took full control of the website and Cook decided to focus on writing and speeches. Reports include Charlie Cook's two weekly columns for National Journal magazine and National Journal Daily. In addition, changes are generally made each week to The Cook Political Report's House, Senate, and Governors At-A-Glance charts, which list all congressional candidates (together with known potential candidates) running in each state and district in the country. All House and Senate contests are rated on a seven-category scale; the seven categories are Solid Democratic, Likely Democratic, Lean Democratic, Toss-Up, Lean Republican, Likely Republican, and Solid Republican. The Cook Political Report with Amy Walter uses the Cook Partisan Voting Index (the PVI), which lists each congressional district in the country according to propensity for voting Democratic or Republican. Every four years following a presidential election, the PVI is updated to reflect how Democratic or Republican a district is based on how that district voted in the presidential election compared with the rest of the country.

Cook also listed seven states as "toss-ups": Colorado, Florida, Iowa, New Hampshire, North Carolina, Ohio, and Virginia. Obama ended up winning all of these states except for North Carolina.
