Two-term Senator Bob Casey raised just over $211,000 during the second fundraising quarter and, for the first time since his re-election last year, brought his total cash on hand to six digits. He has more than $142,000.

These numbers show a marked difference from Casey’s first quarter totals, when he brought in a mere $66,000 and had just less than $55,000 cash on hand. Casey could be forgiven for these numbers as he had just come off a successful re-election campaign and thus had six years to raise money. These days, though, it’s never too early to start thinking about your next election.

The Senator has clearly learned this lesson since he raised about triple the amount he did this point six years ago ($71,000) during his first re-election campaign. Back then, he also had about a hundred thousand dollars less on hand than he does today.

Casey’s total was greatly aided by the $27,500 he received in donations from political action committees (PACs). His biggest donation was the $4,000 he got from the National Gas Association. Yet he also was given $2,500 by CISCO Systems and Pfizer. Finally, he received several gifts of $1,000 from the PACs of companies like GlaxoSmithKline, Google, and Bristol Myers Squibb.

So far, Casey has faced little electoral trouble in his career as a Senator. He defeated incumbent Senator Rick Santorum in 2006 by a wide 59%-41% margin, and in 2012 won re-election 54%-45%, while running two points ahead of President Obama. He will next be on the ballot in 2018.

Any money he raises for Senate would be transferrable should Casey want to explore a bid for Governor.
