Two groups co-founded by former George Bush advisor Karl Rove have hit the $100 million mark in total fundraising this election cycle.

Politico:

American Crossroads, the pro-Republican super PAC co-founded by Karl Rove, and its nonprofit affiliate Crossroads GPS, will announce $100 million raised for both so far through the 2012 cycle, officials told POLITICO.

The cash haul runs through all of 2011 and includes the first quarter of this year, running through March 31. The announcement will come officially Friday, at the same time the monthly fundraising filings become public.

Steven Law, president and CEO of American Crossroads and Crossroads GPS, said, "Our supporters are alarmed about where President Obama is taking the country, and they feel that by supporting Crossroads, they can do something about it. We had thought the primary season might temporarily dampen enthusiasm for our efforts, but it seems to have only fired people up."

The figure -- $99,800,000 to be exact -- is about $51 million in 2011, and nearly the same amount, $49 million, in the first quarter of 2012.

American Crossroads will also report $24.4 million in cash on hand. Crossroads GPS won't report a cash on hand figure, officials said.

Crossroads is expected to play a critical role helping the Republican ticket, especially as Mitt Romney scrambles to raise money now that the general election is at hand.

Note that American Crossroads raised almost as much in the first quarter of 2012 as it did for all of 2011.

This certainly puts American Crossoroads on track to raise between $200-$300 million for the election. Along with other GOP Super Pacs, it is possible that conservative groups can raise half a billion dollars to defeat President Obama.

That will even the playing field somewhat. But in addition to what Obama raises directly for his campaign, he will have his own Super-Pacs and labor unions that could up his total to close to a billion dollars being spent on his behalf (unions alone spent around $400 million in 2008 electing Obama and the Democrats).

Nevertheless, Rove's groups and others will keep Romney in the ballpark and give him a fighting chance this fall.
