Drudge says McCain has made his Veep pick and will leak it at 6 tonight. McCain, however, denies:

Looking toward his turn in the spotlight, Republican presidential nominee-in-waiting John McCain said Thursday he had yet to decide on a running mate. McCain was expected to name his vice presidential pick this week, possibly Friday. The hope is to curb any uptick in polling that Democratic nominee Barack Obama could get from his convention, which wraps up Thursday, and to create momentum heading into the gathering of GOP delegates for McCain next week in St. Paul, Minn. McCain and his running mate are expected to appear together for the first time at one or more rallies, including one planned for Saturday in Pennsylvania. McCain said in an early morning radio interview that he was bringing along to that event both former Pennsylvania Gov. Tom Ridge and former Massachusetts Gov. Mitt Romney, two of the leading names on his short list. But he cautioned against assuming that meant either one would be the pick. “I haven’t decided yet so I can’t tell you,” he told KDKA NewsRadio in Pittsburgh early Thursday.
