The Center for Responsive Politics’ OpenSecrets site just added expenditures by Senate campaigns to their site. The data was released by the Federal Election Commission for the first time last week. CRP has a detailed listing of all the expenses incurred by the committees, the recipients and the dates of the expenditures. For instance, we know that in the 2010 cycle Sen. Harry Reid, D-Nev., spent more than $31,000 for catering at the Charlie Palmer Steakhouse.

And a quick search on our Party Time data shows that at least four fundraisers for Reid were held at the venue and many of the payments were made just around the dates of the fundraisers.

We plan to download the entire data from CRP and run more matches next week.
