  We show that for a typical fundamental discriminant $D,$ the partial sums of
the real character $\chi_D$ change sign $\gg (\log\log D)/\log\log\log \log D$
times on a very short initial interval (which goes beyond the range in
Vinogradov's conjecture).
  We also prove that the number of real zeros (localized away from $1$) of
Fekete polynomials associated to a typical fundamental discriminant is $\gg
\frac{\log\log D}{\log\log\log\log D}.$ This comes close to establishing a
conjecture of Baker and Montgomery which predicts $\asymp \log \log D$ real
zeros.
  These results rely crucially on quantitative estimates for the joint
distribution of $-\frac{L'}{L}(s, \chi_D)$ at several points $s$ in the
vicinity of the central point $s=1/2$, as well as concentration results for
$\log L(s,\chi_D)$ in the same range, which we establish.
  In the second part of the paper, we obtain, for large families of
discriminants, non-trivial upper bounds on the number of real zeros of Fekete
polynomials, breaking the square root bound. Finally, we construct families of
discriminants with associated Fekete polynomials having no zeros away from $1.$
