The Cook Political Report
The Cook Political Report is an independent online newsletter that analyzes elections and campaigns for the United States House of Representatives, the United States Senate, Governor's offices and the American Presidency. It was founded by political analyst Charlie Cook in 1984. Coverage of Senate and Gubernatorial races is headed up by Editor Jessica Taylor and coverage of House races is led by David Wasserman. Amy Walter serves as national editor.
Reports include Charlie Cook's two weekly columns for National Journal magazine, and NationalJournal Daily. In addition, changes are generally made each week to the House, Senate, and Governors At-A-Glance charts, which list every candidate running in each state and district in the country, in addition to other candidates who are rumored to be considering a run. The House Summary lists the current makeup of the House of Representatives, as well as all announced retirements, potential retirements, and candidates possibly running for higher office. All House and Senate contests are rated, regardless of competitiveness on a seven-point scale; Solid Democrat, Likely Democrat, Lean Democrat, Toss-Up, Lean Republican, Likely Republican, and Solid Republican.
The Cook Political Report employs what it calls the Cook Partisan Voting Index, 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.
Previously a hard copy publication, the Cook Political Report moved to an all online format in 2004.
Past predictions
2012
In the presidential election, Cook rated 21 states as at least leaning toward the Democratic candidate, Barack Obama; Obama won all 21 of these states. The report rated 23 states as at least leaning toward the Republican nominee, Mitt Romney; Romney won all 23 of these states. Cook also listed seven states as "toss-ups": Colorado, Florida, Iowa, New Hampshire, North Carolina, Ohio, & Virginia. Obama ended up winning all of these states except for North Carolina.In the race for control of the US Senate, Republican candidates won every Senate seat that Cook listed as at least leaning Republican, while Democrats won every Senate seat that Cook listed as at least winning Democratic. Cook listed ten Senate races as "toss-ups"; Democrats ended up winning eight of these, while Republicans won the other two.
Among governor's races, Cook correctly predicted that Republicans would win control of the North Carolina governorship, which Democrats had previously controlled. Cook also listed three Democratic-held governorships as "toss-ups": Washington; Montana; & New Hampshire. Democrats ended up holding onto all three.
2014
In the race for control of the US Senate, Cook correctly predicted that Republicans would win control of the Democratic-held Senate seats in Montana, West Virginia, & South Dakota. Cook also listed nine US Senate races as toss-ups; Republicans ended up winning eight of these, while Democrats won only one. Every state Cook listed as at least leaning Republican voted Republican; every state Cook listed as at least leaning Democratic voted Democratic.Among governor's races, Cook correctly predicted that Democrats would flip the Pennsylvania governorship and that Republicans would flip the Arkansas governorship. Democrats won every state Cook rated as at least leaning Democrat; Republicans won every state Cook rated as at least leaning Republican. Cook also rated 13 governor's races as "toss-ups". Democrats ended up winning 3 of these, while Republicans won the other 9; an independent, Bill Walker, won the toss-up governor's race in Alaska.
2016
In the race for control of the US Senate, Cook rated seven Senate seats as "toss-ups", suggesting the two parties had roughly even odds of winning each election. In the end, Democrats won two of these elections and Republicans won five. Cook contributors had expected the toss-up races to break the other way, with Democrats winning most of them. However, Republicans did not win any Senate races that Cook identified as at least leaning toward Democrats; nor did Democrats win any Senate races Cook identified as at least leaning toward Republicans.In the presidential election, Cook predicted that Hillary Clinton would win Pennsylvania, Michigan, and Wisconsin; it also rated North Carolina, Florida, Maine's 2d Congressional District, and Nebraska's 1st Congressional District as "toss-ups". In the end, Trump won all of these states and districts, though for the most part by narrow margins. All of Cook's other final predictions for the presidential election were correct, though Cook had speculated earlier in the year that Democrats had a chance of success in states they did not end up winning, including Arizona & Texas.
Among governor's races, Republicans won every governorship that Cook rated as at least leaning Republican, while Democrats won every governorship Cook rated as at least leaning Democratic. Cook listed six governorships as toss-ups: Missouri, New Hampshire, Vermont, West Virginia, Indiana, & North Carolina. Republicans won Missouri, New Hampshire, Vermont, & Indiana, while Democrats won North Carolina & West Virginia; the newly-elected Democratic governor of West Virginia, Jim Justice, switched to the Republican party only seven months into his term.
2017
New Jersey & Virginia each had open races for governor in 2017. Cook listed the Virginia race as "Lean Democratic" and the New Jersey race as "Likely Democratic". Democrats ended up winning both races by wide margins.2018
In the race for control of the US House of Representatives, Cook listed 210 seats that at least leaned toward the Democrats; 194 seats that at least leaned toward the Republicans; and 30 seats that were "toss ups". Democrats ended up winning 235 seats, including all of the seats that Cook listed as at least leaning Democratic, as well as most of the "toss ups". However, Cook incorrectly predicted that Republicans would hold onto several seats that Democrats ended up winning, including Oklahoma's 5th Congressional District; South Carolina's 1st Congressional District; & New York's 11th Congressional District.In the race for control of the US Senate, Democrats won every seat that Cook listed as at least leaning Democratic, while Republicans won every seat Cook listed as at least leaning Republican. Cook also listed 9 Senate races as toss-ups; Democrats won four of these races, while Republicans won the other five.
Among governor's races, Democrats won every seat that Cook listed as at least leaning Democratic, while Republicans won every seat Cook listed as at least leaning Republican. Cook also listed 12 governor's races as toss-ups; Republicans & Democrats ended up each winning 6 of these.
