Ever had a date you didn't want to introduce to your mother? Bill White knows how you felt. The Democratic nominee for governor will campaign today in Midland, Abilene and Alvarado. Where he won't be is in Austin and Dallas, where Barack Obama, the leader of White's party, will be holding two fundraisers and giving a speech on higher education — and, it turns out, meeting briefly with Rick Perry to talk about border issues. It remains to be seen whether avoiding the president is a plus or a minus in what is already an uphill battle to oust a 10-year incumbent.
