The DNC will have to try end runs.
This impact their voter rolls.
Illegals, the Incarcerated and the fraudsters are 99% of the DNC base.
Actually, fraud and illegals don't comprise more than about 1-2% of the vote in any state or district. And, the Dems don't really use it unless they need it. In battleground states thats why the GOPers need a margin of more than 1% to win because otherwise the Dems will steal it away. With compliant election commissioners they can manufacture (fraudulently issue) 1,000 - 5,000 votes but anything more is next to impossible. They might be able to register tens of thousand of illegals in a larger state. But they still can't alter an election outcome that isn't already squeaker close.
Frankly, I think that 2008 was a banner year for Dem election strategy. They stole the Senate election for Al Franken (margin 312 votes out of 2.4 million) and Mark Begich won in Alaska by 3800 votes out of 400,000 cast -- only after a false accusation of wrongdoing by a federal prosecutor.
Liberal democrats are an agressive, metastatic, invasive, and terminal CANCER to the US. It is only a matter of time, and they know it...
