She tried being (somewhat for her) nice to Obama leading up to Super Tuesday. It did not work. She fired her campaign manager and took the gloves off for the last few primaries, sharpening her attacks on Obama. She has gotten thoroughly thrashed since then (it's 10 in a row now). The conventional wisdom is that negative campaigning works. Well, it did not work in Wisconsin for Hillary, as Obama beat her by more than two touchdowns (58%-41%).
So, does she play nice and try to win by drawing contrasts with Obama, or does she turn her negativity amp up to 11 to try to squeeze out wins in Texas and Ohio on March 4? I think I know the answer to that query.
And, this brings me back to where I started in this election process. People do not like Hillary Clinton. They like the IDEA of Hillary Clinton.
