Care Act, two Republicans, Daniel Chavez, a utility company employee from Mission in Hidalgo County, and Bryan Keith Underwood, a carpenter from Seguin in Guadalupe County, filed for their party's nomination. Underwood polled 13,599 votes (74%) to Chavez's 4,794 (26%). Underwood raised more funds than Cuellar's previous Republican opponents, but questions were raised in his hometown newspaper, the Seguin Gazette, about his criminal record, which included a guilty plea for a felony criminal mischief charge, which is normally a misdemeanor. Underwood had also refused on one occasion to present his identification to a law enforcement officer. Cuellar prevailed, as expected, with 62,055 votes (56%) to Underwood's 46,417 (42%). The remaining 1,880 votes (2%) went to Libertarian Party candidate Stephen Kaat. While Underwood won Guadalupe, Wilson, McMullen, and Atascosa counties, Cuellar's margin in Webb County (25,415 to 3,569) was more than enough assure him a seat in the incoming Republican-majority House. 2012 Cuellar was opposed in the November 6 general election by Republican William R. Hayward and Libertarian Patrick Hisel. Hisel ran unsuccessfully as a Libertarian in 2010 against Republican U.S. Representative Kay Granger from the Tarrant County-based 12th district. Guadalupe County, a Republican stronghold that usually opposed Cuellar for reelection, was removed from the reconfigured 28th district. Cuellar defeated Hayward, 112,262 (68%) to 49,095 (30%). Hisel took 2% of the vote, and a Green Party candidate received the remaining 1%. 2014 Cuellar faced no Republican opposition in 2014. Then Webb County Republican chairman Randall Scott "Randy" Blair of Laredo criticized Cuellar's 2010 vote for Obamacare but said the GOP could not find a candidate because of Cuellar's personal popularity, political longevity, occasional cooperation with Republicans, and strong campaign organization. 2016 Cuellar won a rematch in the March 1, 2016, Democratic primary with former Republican congressional candidate William R. Hayward, who switched parties to run again for the House. Cuellar received 49,962 votes (89.8%) to Hayward's 5,682 (10.2%). Cuellar then defeated Republican Zeffen Patrick Hardin in the November 8 general election, 122,086 (66.2%) to 57,740 (31.3%). Green Party nominee Michael D. Cary received 4,616 votes (2.5%). 2018 In the general election held on November 6, 2018, Cuellar overwhelmed his lone challenger, Libertarian Arthur Thomas, IV, 117,178 votes (84.4%) to 21,647 (15.6%). 2020 On January 11, 2019, the progressive organization Justice Democrats, which supported U.S. Representative Alexandria Ocasio-Cortez's successful 2018 primary campaign in New York City, announced that it was seeking a
