Without winning BIG in Philly and Pittsburgh, the Democrats have a hard time winning Pennsylvania.
If the GOP wants to have the slightest chance in Pennsylvania this November, they will hire poll watchers to literally stand in each voting precinct in Philadelphia and Pittsburgh to make sure the Dems don't "stuff" the ballot in the strong Democrat (union controlled or strong minority) precincts where there are no credible Republican counterparts to even check the voting process.
For example, if there are 123 people registered to vote on a certain block, there will be 123 guaranteed votes cast for whichever candidate the Dem machine wants the votes cast for.
Without a GOP poll watcher, all it takes to vote is a warm body (no ID) to walk in and pull the lever.
In some precincts, the voting place is literally a renovated basement inside someone's rowhome, or maybe a local business which has found favor with the political machine.
Bottom line: If Carl Rove or the GOP powers-that-be want to have a chance, they will find a way to doublecheck voting in the inner city.
I believe the GOP would gain at least 4-percent if they could eliminate fraud.
I've already written Rove twice suggesting that very thing, but I don't know if it will do any good.
Problem is if the Reps go into those precincts and attempt to keep an eye on what's going on there, we will be accused of trying to intimidate voters. We lose anyway you slice it.
