Turn the section font from bold to roman in a table of contents

Question

I have some trouble using the titletoc package to edit a simple ToC composed only of several sections. I would just like to turn their font from bold (which is the default font) to roman, but I am definitely making some mistake with the \titlecontents command. Here is an example:

\documentclass[12pt,a4paper]{article}
\usepackage[margin=3cm]{geometry}
\usepackage[authordate,backend=biber]{biblatex-chicago}
\bibliography{bibliography}
\usepackage[tiny]{titlesec}

\usepackage{titletoc}
% \titlecontents ???

\begin{document}
\tableofcontents
\section[Reference A]{\fullcite{bibtexkey A}}
\section[Reference B]{\fullcite{bibtexkey B}}
\section[Reference C]{\fullcite{bibtexkey C}}
\end{document}

Answer 1

You can specify the font in the \titlecontents command:

\documentclass[10pt,letterpaper]{article}
\usepackage{lipsum,titletoc}

\titlecontents{section} % set formatting for \section -
                        % \subsection must be formatted separately 
[2.3em]                 % adjust left margin
{\rmfamily}             % font formatting
{\contentslabel{2.3em}} % section label and offset
{\hspace*{-2.3em}}
{\titlerule*[1pc]{.}\contentspage}

\begin{document}

\tableofcontents

\section{Joe}
\lipsum

\section{Blow}
\lipsum

\end{document}

which gives you:

titlesec and titletoc are nice but getting the arguments right is a bit challenging, a key-value interface would be easier.
