Sam Brownback, who missed more than a third of the votes in the U.S. Senate during his unsuccessful presidential run, was far less truant during his successful run for Kansas governor. The Washington Post's database has Brownback missing just 12 votes this year, or 1.9 percent of Senate votes. That compares with Sen. Pat Roberts' 43 missed votes, or 6.7 percent, for the year so far. In the House, Rep. Jerry Moran, R-Hays, managed to run a winning campaign for U.S. Senate while missing 124 votes, or 8 percent. Rep. Todd Tiahrt, R-Goddard, missed 144 votes, or 9.3 percent, while running his unsuccessful Senate campaign. The database shows Rep. Lynn Jenkins, R-Topeka, with perfect attendance and 1,555 votes cast, and retiring Rep. Dennis Moore, D-Lenexa, missing 2 percent of votes.
