UPDATE: Folks, please be careful with the information you put into these spreadsheets. They are for informational purposes only. If folks are going to put inaccurate or intentionally misleading information into these sheet, I will be forced to cut off access to them.
Below is a Google spreadsheet showing the Senate incumbents and challengers who have filed a DOI as of yesterday. The Senate did not renumber their districts, thus incumbents are running under the same district number they currently represent. As with the House spreadsheet, please add any announced challengers – no rumored candidates or trial balloons please. Also please update the sheet if you see any errors.
