Sioux City, IA -- While families in Iowa are already beginning to feel the effects of the job-killing Obamacare, Congressman Braley and the Republican candidates vying to replace Senator Harkin have unfortunately either been on the wrong side of the issue, have issued conflicting statements or have been curiously silent. In contrast and with the realization that now is not the time to add more timid or wrongheaded politicians to the current Washington class, Sam Clovis today signed the Senate Conservatives Fund’s Pledge to defund Obamacare and echoed his previous comments in support of Senator Mike Lee’s efforts to do the same.
