Candidates for the House and Senate and the PACs that support (or oppose) them have spent about $19.47 for every second since the current election cycle began in January of 2013, according to data from the Center for Responsive Politics.
It's important to note that this is only what has been reported. Certain types of spending aren't reported because they either don't need to be or because they fall into a legal gray area -- or both.
These numbers are so large that it's hard to put them into perspective. So we took the total amount spent and figured out how much was spent every second of this campaign cycle. And while you were reading the text above, this little tool here had been figuring out how much each type of campaign has spent, if they were spending their per-second average while you were otherwise distracted.
The election is in fewer than 50 days. There's much more spending to come -- perhaps as much as has already been laid out in the entire cycle up until now. So, consider the numbers ticking away up there to simply be estimates. Low-ball estimates.
