U.S. Sen. Bob Casey keeps piling up the campaign cash and bragging about it.

The Scranton Democrat’s campaign said today it raised $2.2 million in the first quarter of this year and ended the quarter with more than $10 million cash on hand, up from $8.6 million at the end of 2017.

The campaign said the first-quarter haul was the largest for a Senate candidate in state history with 91 percent in donations of $100 or less and the money coming from 66 of 67 counties.

I asked Rep. Lou Barletta’s campaign for their numbers, but spokesman Jon Anzur said they won’t announce until next week. They’re not required to file campaign finance reports that become public until Sunday, April 15.

Campaigns that think they raised a lot of money tend to get the word out before they have to file.

Barletta ended 2017 with more than $1 million on hand. He had quite a bit of catching up to do and started with suspicions about his ability to raise money. That Franklin & Marshall College poll last week that showed him 18 percentage points behind Casey won’t inspire donor faith, even if it did have a rather large margin of error, plus or minus 6.8 percentage points.

Rep. Jim Christiana is challenging Barletta for the Republican nomination, but no one gives him a chance.
