At WREX, we use Newsroom Solutions and XPression, and have successfully for about 4 years, now.
We contacted NS and had them set up an .xml of our election data, which they created on our local server. We then used that .xml as a DataLinq source by using the RSS DataLinq type. Each race then has its own set of scenes for display. Some for full-screen with headshots, some as an on-camera overlay.
I know other stations have been able to use a variation of t-prompt and CII to push this info from NS to XPression, but I have not personally gone that route.
