It’s the universities and high-tech companies piling up dollars for President Barack Obama, while the banks are spending even more for Governor Mitt Romney, according to the latest campaign contribution numbers compiled by MapLight.org.

And in the home stretch of the 2012 election, MapLight and the technology magazine Wired have jointly created an embeddable “influence tracker widget” to help readers follow the money behind the candidates. The widget features candidates’ total contributions, a list of their top 10 donors, their ranking as a fundraiser within the office they seek, and their ranking overall among candidates running at the federal level.

In a clever touch, corporate logos of candidates’ top contributors are displayed virtually on Obama and Romney’s business suits, like a NASCAR sponsor.
