Query: A common origin for the resistivity of Cd$_2$Re$_2$O$_7$, the cuprates,
  and Sr$_2$RuO$_4$?   We propose an explanation for the temperature dependence of the resistivity
of Cd$_2$Re$_2$O$_7$, including the regime above the structural phase
transition at $T$=200 $^o$K. The mechanism involved relies on the existence of
a strong van Hove singularity close to the Fermi surface, which is evidenced by
relevant band structure calculations. The same mechanism has successfully
described the $T$-linear resistivity of the cuprates and Sr$_2$RuO$_4$, and the
one-particle scattering rate in the former materials, as corroborated by recent
experiments. We describe a few predictions for Cd$_2$Re$_2$O$_7$ and
Cd$_2$Os$_2$O$_7$.
