Although it’s thoroughly amusing to watch GOP leaders Rush Limbaugh and Newt Gingrich as they engage in manly Spartan wrestling for the soul of the Republican Party, it’s clear that neither of them appears to understand politics in terms of anything more than personal self-aggrandizement.

For all their bluster, the GOP has not been able to recruit serious challengers to Blanche Lincoln and Harry Reid, the two most vulnerable Senate Republicans Democrats up for re-election in 2010. And the man tasked with doing that seems rightly worried about the influence that Limbaugh and Gingrich are having on the party:

A top Senate Republican is taking aim at recent statements from conservative commentators Rush Limbaugh and Newt Gingrich suggesting Supreme Court nominee Sonia Sotomayor is a "racist."

"I think it’s terrible," Sen. John Cornyn, the chairman of the National Republican Senatorial Committee, told NPR’s "All Things Considered" Thursday. "This is not the kind of tone any of us want to set when it comes to performing our constitutional responsibilities of advise and consent.”

The Wall Street Journal counsels Republicans to "act like grown-ups," and remember that "they often have the better argument." Nice try.

The soul of the GOP shines through in the rhetoric of Limbaugh and Gingrich, which continues to thin the GOP herd — the percentage of self-identified Republicans is the lowest it’s been since 1983.

Nobody’s going to want to be 2010 cannon fodder for the Party of Lose.
