AUSTIN, Texas (AP) — Texas Gov. Rick Perry is hosting a series of dinners with potential donors this week as he moves toward an announcement of his White House aspirations.Perry has said he'll announce by the end of this month whether or not he will seek the Republican nomination for president in 2012. In the meantime, he's doing his homework to make up his mind.Spokesman Mark Miner says the three meetings in Austin this week are intended to "determine whether they have the resources to fund an effective campaign." Miner says the meetings are just part of the "decision-making process."Perry has kept a busy summer schedule despite having back surgery July 1. He's had multiple meetings with fundraisers and made several trips to conservative events around the country.
