In the political world where money reigns supreme, Sen. Pat Toomey holds a substantial lead over his three Democratic challengers.

Toomey’s re-election campaign raised $1.9 million over the last three months of 2015, bringing the junior Senator’s cash on hand to $9.6 million, Laura Olson of the Morning Call reports.

Katie McGinty’s Senate campaign raised less than half of what Toomey raked in over the quarter, just $980K. The former Chief of Staff for Gov. Tom Wolf now has $1.2 million to spend before the April 26th primary.

Democratic frontrunner Joe Sestak had $2.4 million in cash on hand at the end of September, while John Fetterman brought in a solid $168,000 in his first weeks in the race.

The Toomey campaign received 27,590 contributions in 2015, with 85% of those under $200, campaign manager Peter Towey wrote in a Jan. 7th email to County GOP chairs.

Full FEC financial disclosure reports are due Jan. 31st.
