With redistricting on the horizon, the Republican Governors Association (RGA) had its largest fundraising quarter to date. The committee has pulled in $18.9 million since the end of March and now has some $40 million cash on hand, according to a release.

"For three and a half years, we have been implementing a plan to secure a majority of governors and rebuild the Republican Party from the state level," Nick Ayers, the RGA’s executive director, said in a statement. "Our disciplined approach is paying off, and we are in position to inject precious resources behind quality candidates who will win, govern effectively and broaden our base."

The RGA's previous largest fundraising quarter — in which it pulled in $11.9 million — occurred in the fourth quarter of 2009, when it was fighting to win elections in Virginia and New Jersey.

The committee has raised $28 million in 2010.

"The Republican Governors Association has the momentum, message and money needed to make massive gains this November," said Ayers.

Republicans and Democrats are focused on governors' races this cycle because, once in office, they play a significant role in most states’ redistricting processes.

The Democratic Governors Association has yet to release its second-quarter numbers.
