As the Republican presidential field jockeys not only for positioning heading into the home stretch before the primary season but also attempts to pad their campaign coffers for that run, you might catch them crack a smile on Wednesdays. A Smart Politics review of the tens of millions of dollars that have flowed into the campaigns of the Republican field in 2011 finds that a plurality of money – 19.7 percent – has come in on Wednesday. That is slightly higher than Monday (18.8 percent), Tuesday (18.4 percent), Thursday (18.1 percent), and Friday (17.8 percent). Only a small fraction of campaign contributions are received on Saturday (3.8 percent) and Sunday (3.5 percent). This data excludes the last day of the quarterly fundraising cycles (March 31, June 30, September 30 etc.), in which contributions skyrocket in a last minute attempt to boost numbers. (Contributions on such days can be 10 to 20 times that of an average day).
