Dallas ? President Bush added a side trip to his Texas ranch to vote in Tuesday’s Republican primary after aides apparently forgot to order an absentee ballot.

Bush hasn’t missed a GOP contest since he started voting in Crawford in March 2002. An administration official, speaking on condition of anonymity, indicated Saturday that White House staff had slipped up on the paperwork for requesting a mail-in ballot this time.

Early Saturday, with the president at risk of missing the election, the White House announced he would fly to Crawford after a meeting with the Russian foreign minister at the White House. He’ll arrive at the polls before the 7 p.m. closing.
