  We consider the generation of the baryon asymmetry in the two-Higgs doublet
model. Investigating the thermal potential in the presence of CP violation, as
relevant for baryogenesis, we find a strong first-order phase transition if the
extra Higgs states are heavier than about 300 GeV. The mass of the lightest
Higgs can be as large as about 200 GeV. We compute the bubble wall properties,
including the profile of the relative complex phase between the two Higgs vevs.
The baryon asymmetry is generated by top transport, which we treat in the WKB
approximation. We find a baryon asymmetry consistent with observations. The
neutron electric dipole moment is predicted to be larger than about 10^{-27}ecm
and can reach the current experimental bound. Low values of tan\beta are
favored.
