In 2008 the National Republican Senatorial Committee spent millions of dollars in Republican primaries to keep incumbents in office and keep dynamic challengers with new ideas and real drive for reform out of office. They supported candidates like Charlie Crist and Arlen Specter who took their money and then left the Republican Party. They supported insider hacks like Trey Grayson against grassroots candidates like Rand Paul. In many cases their efforts failed, but in several states they likely cost Republicans seats in the Senate. If the money they spent in primaries had been saved for the general election Republicans might well control the Senate today. The NRSC's record for 2010 was disastrous for the party and they squandered the money of their contributors.
A lot of rank and file Republicans saw what the NRSC did in 2010 and decided they'd had enough. Donations to the NRSC are down and as a result their Democrat counterparts have been outfundraising them this year. Republican voters who are serious about reclaiming government for the people are increasingly deciding to give their money to groups they trust and candidates they believe in rather than to establishment groups like the NRSC who have made preserving a status quo of perpetual incumbency their priority. The people want change and the NRSC stands for nothing but more of the same.
Now it appears that the NRSC has learned nothing from their mistakes in 2010 and they are already beginning to use their money and influence to pick winners and losers in the 2012 Republican primaries. They are taking money raised from Republican donors who want a party which has the best candidates and remains true to its principles and giving it to insiders who have already failed the party and failed the people over and over again. Some of those they are supporting are among those Senators who are at the top of the list of those who most Republicans would like to see replaced by new leaders with more conservative principles.
