Sol Sender, designer of Obama's 08 logo, on Hillary Clinton's big pointy H:

If you boil it down it's really a symbol of forward motion. On the Obama work we were really conscious from the start about where he was vulnerable — we knew Obama critics said things like, ‘He's not American.’ So we thought going strong with a patriotic theme was quite important. Hence the red, white and blue colors in the Obama logo. In terms of vulnerabilities, Hillary always seems to get dragged into the past by her critics. Therefore, you might argue that a symbol like this, which is so aggressively pushing forward, could help counterbalance any negative energy that is directed at her past.
