The latest Quinnipiac Poll shows that Joe Sestak is closing in fast on Arlen Specter for the Democratic nomination for Senate in Pennsylvania.

A month ago, Specter was ahead by 53-32. In the latest poll his lead has shrunk to only 47-39, with two weeks to go. This, of course, is the sort of momentum that Scott Brown showed in the closing days of the Massachusetts senate race four months ago.  Specter is the veritable poster child of all that is wrong with Washington. He is a long-time incumbent (first elected to the Senate in 1980) and seems devoid of any political principle beyond getting elected and reelected.

He has switched parties twice for precisely that reason. (To be sure, Winston Churchill switched parties twice also, but he crossed the aisle the first time because he agreed with the Liberal agenda more than with that of the Conservatives and he switched back 20 years later when the Liberals were heading, quickly, toward political oblivion).

If Sestak knocks off Specter, there won’t be a tear shed outside of Specter’s own bedroom, and it will be one more indication that November could be a lot of fun.
