In my humble opinion, in life as in politics, “bold” is a courageous, adventurous, plucky, intrepid move or action that rejects the “we have always done it this way” mentality; that goes against political, racial, religious, gender, age, etc., conventions and prejudices and whatever other walls, barriers, taboos there may be that keep rational, intelligent men and women from making the right decisions for themselves and, in this case, for their country. In effect, using such differences and elimination of “barriers” to truly make good choices.
From such perspective, the boldest Vice Presidential choices McCain and Obama could make would be:
For John McCain, the (relatively) junior Democratic U.S. Representative from Texas, Sheila Jackson Lee.
For Barack Obama, the (relatively) senior Republican U.S. Senator from Texas, Kay Bailey Hutchison.
P.S. 1 The fact that I am from the great State of Texas has nothing to do with these recommendations
P.S. 2 My apologies for the “relative” age comparisons to John McCain and Kay Bailey Hutchison
P.S. 3 I said “bold,” not: “to be counted upon.”
