Why would you be afraid of someone turning out to be a good president who unites the country?
Because it would make the left-wing look bad, which all democrats are afraid of, of course.
In America, the opposition party does everything they can to make sure the President does not succeed. At least today. Well, at least the Republicans with President Obama. Republicans would rather the country suffers tremendously than President Obama be a good president who unites the country.
What I'm afraid of is another Republican President. Especially one that doesn't believe his own child should be able to marry because they're gay. Chris Christie is a moderate only in a far-right party. He'll toe the Tea Party line once he gets out of New Jersey.
