Arlen Specter is getting by with a little help from his Senate friends.

The five-term Pennsylvania Republican, who faces a tough primary challenge from conservative former Rep. Patrick J. Toomey, received donations from 10 Republican senators in the first three months of this year.

The pro-Specter senators, who donated from either their candidate committees or their leadership PACs, include Minority Leader Mitch McConnell of Kentucky; John Cornyn of Texas, the chairman of the National Republican Senatorial Committee; and Lamar Alexander of Tennessee, the Senate GOP Conference chairman.
