Barack Obama won big in South Carolina on Saturday, and this will be seen as good news by Republicans who should be cheering for an Obama win in the Democratic nominating process. The reason is that if Hillary wins the nomination she may decide, or have it decided for her, to ask Obama to run as VP. A Hillary/Obama ticket would be almost irresistible to an electorate eager to parade their willingness to vote for a woman and/or a black man regardless of what they stand for. To put both on the same ticket would make the Democrats very difficult to beat in November.
If Obama wins the nomination, however, it's unlikely that Hillary would be willing to serve as his Vice President. The nature of the office would be deemed beneath her station, and she would likely choose to remain in the Senate. If so, the Democratic offering would be weaker with Obama at the head than with him as the running mate.
