It's not just Democrats complaining about Kerry

A recent issue of Asia Times, in anointing Bush as Reagan's heir as the Teflon president, also notes Kerry's failure to gain traction:

Kerry, on his part, has thus far not focused on Bush's performance in general, and in particular on the low-gear performance of the US economy. When Bill Clinton won his first presidential term, his campaign battle cry was, "It's the economy, stupid!" Thus far, Kerry's lack of focus on a similar or the same battle cry has enabled Bush's Teflon presidency to maintain an edge over him.

Of course, as previously noted, Kerry really isn't in a good positoin to gain traction on Iraq due to his past votes. Realistically, it's going to take Bush losing traction.
