In addition to the phone calls, Bachmann also placed banner ads on websites in those states, along with New Hampshire, linking to an anti-Obama petition on her website, posted multiple message on Facebook and Twitter and put out an official statement on the speech, according to a Bachmann insider granted anonymity to speak candidly about strategic matters.

The bevy of Bachmann-related activity around the Obama address amounted to a test run of her national operation, said the source. “What was important to us was to do this at the drop of a hat on a subject we did not necessarily see coming,” the source added.

Bachmann said earlier this week that while she initially planned to announce her presidential plans in June, she might move up that deadline.

With former Arkansas governor Mike Huckabee now out of the race, Bachmann is the most high-profile social conservative moving toward the race. (Former Alaska governor Sarah Palin would likely overshadow Bachmann if she ran but no one knows what the 2008 vice presidential nominee is planning when it comes to 2012.)

While Bachmann is seen as having only a longshot chance at the nomination, she is expected to do well in Iowa where she was born and where her strident social conservative message and charisma on the stump should all play well.

Bachmann is also a proven fundraiser. She collected more than $13 million for her House race re-election in 2010 — a stunning amount for a Congressional race — and raised $1.7 million in the first three months of 2011.
