As Wayne Slater of the Dallas Morning News points out, John McCain is quietly engaged in the delicate courtship of Catholic voters. A key swing demographic, Catholics could crown McCain victorious come November. However, the generally moderate group could also be turned off if McCain lines up too closely with the religious right. Thus, tact is of the utmost importance as the Senator handles incidents like John Hagee’s endorsement. As part of their effort to win Christian voters, the McCain campaign has dispatched Senator Sam Brownback to spread the good word.
