Iowa’s two U-S senators split the vote on a measure to increased federal borrowing. The measure, which passed 68-to-29 Tuesday, raises the debt ceiling, which has been capped at five point-9-5 trillion dollars. President Bush had asked Congress for 750-billion more in borrowing authority, but he got 450-Billion. Iowa’s democrat senator Tom Harkin voted no, GOP senator Chuck Grassley voted for the higher debt ceiling. Democrats who control the senate protest that the borrowing wouldn’t be necessary if the president hadn’t cut federal revenues with a generous tax cut last year. The House is likely to sidestep a similar roll-call vote entirely and attach the higher debt ceiling proposal to some must-pass bill like anti-terrorism legislation.
