WASHINGTON — The success of President Barack Obama’s starkly liberal second-term agenda will rest largely on the shoulders of Senate Majority leader Harry Reid, who has been a rock-solid political ally and a valued legislative tactician for Obama during his first term.
But for the first time since Obama became president four years ago, his political interests and Reid’s may be diverging. Not so much because there is huge disagreement on the president’s agenda, but because helping Obama may hurt vulnerable Democrats in the Senate.
