The Texas Ethics Commission now requires political candidates to document their political spending in specific categories — advertising, consulting, polling, etc. — allowing the public to better understand campaign-finance filings. (See related story). This interactive bubble chart visualizes those spending categories by candidate, political party and election type in the second half of 2010. Use the drop-down menus for bubble size, labels and colors to change the views by category or reorder the data. Read our campaign-finance topic page for background.
