One year after his decisive loss to Sen. Barbara Mikulski, former Queen Anne’s Commissioner Eric Wargotz (R) has decided against taking on another popular Maryland Democrat in 2012.

After mulling a campaign for several months, Wargotz announced Thursday night that he would not challenge Sen. Benjamin Cardin (D), who is set to launch his reelection bid Sunday.

Wargotz said in a statement that he believed he would have been “well positioned” to win the Republican nomination against Cardin.

“Unfortunately, support for the incumbent Senator (and the President) remains strong in Maryland, despite the national political environment,” Wargotz said. “In this political reality, we find ourselves in the position of being able to win the Republican nomination but falling short in the general election.”

Former Secret Service agent Daniel Bongino has been actively campaigning for the Republican nod for several months, and Del. Patrick McDonough (Baltimore County) is also considering a run.

Though he lost to Mikulski by 26 points, Wargotz had one asset for another race that Bongino does not — personal wealth. Wargotz raised $932,000 for his 2010 campaign, with more than two-thirds of that amount coming from his own wallet. Cardin had $2.3 million in the bank as of Sept. 30.
