All those who find Obama's promise of "Change" resonating deep inside them should "make sure" (Obama's favorite phrase) to read today's lead op-ed in the Wall Street Journal, "A Liberal Supermajority."
An Obama victory would give the Democrats control of the presidency and both houses of Congress. Obama, Nancy Pelosi, and Harry Reid would be running the show for at least the next two years. The last time we had a 3D government (Carter's 4 years, and Clinton's first 2 years) it ended badly for the Democrats, since it ushered in the Reagan presidency and handed Congress over to the Republicans in 1994.
Imagine if Obama were able to achieve his heart's desire, such as universal health care, increased regulation of business and financial markets, expansion of union power, higher taxes, government power to regulate CO2 emissions (a key priority according to Obama's energy advisor Jason Grumet would be to declare CO2 a dangerous pollutant, thus giving the EPA authority to set emission limits on power plants and manufacturers), and revival of the Fairness Doctrine, to name just a few. Is this the sort of change that you had in mind?
If it isn't, you should vote for McCain, even if it means holding your nose. A divided government would surely mean less expansion of government power and more room for the economy to fix its own problems.
