Jagler worked in radio broadcasting for over 20 years, most of it spent at WTMJ radio in Milwaukee.[3] For several years he was the co-host of Wisconsin's Morning News with Gene Mueller.[3] He also started a communications and media consulting firm, Jagler Communications, which he still owns and operates.
The 37th Assembly district was significantly redrawn in the controversial Republican redistricting act of 2011 (2011 Wisc. Act 43). The previous representative of the 37th district, Democrat Andy Jorgensen, was drawn out of the district entirely, residing in what was—after 2011—the 43rd district, and leaving the 37th district an open seat. The new 37th district was heavily gerrymandered to create a Republican-majority district, and it resulted in a flood of Republican candidates entering the primary for the open seat. Jagler was endorsed by Speaker Fitzgerald and the entire Assembly Republican leadership.[5] He also received substantial support from other Republican officeholders, including, significantly, State Representative Joel Kleefisch, whose 38th Assembly district previously covered much of the territory of the new 37th district.[6] Kleefisch was also, notably, the husband of the new Lieutenant Governor of Wisconsin, Rebecca Kleefisch, with the Kleefisches also being former broadcast reporters. In the August primary, Jagler cruised to victory over his four opponents.[7] He went on to win the 2012 general election with 55% of the vote over Democrat Mary Arnold.[8] Jagler is now serving his fifth term.
Shortly after the 2020 election, where State Senator Scott L. Fitzgerald, brother of former Speaker Jeff Fitzgerald, was elected to the United States House of Representatives, Jagler announced his candidacy for Fitzgerald's state senate seat. Jagler once again faced a crowded primary field[9] and received substantial support from the party; he was immediately endorsed by Scott Fitzgerald.[10] Jagler prevailed in the February primary with 57% of the vote,[11] and went on to defeat Democrat Melissa Winker in the April special election.[12]
