So what should conservatives do? First off, they should stop talking impeachment. It's a waste of time and effort. It serves no purpose. It is not principled to talk impeachment; it is idiotic. There are zero Democrats in the Senate who would vote to convict Obama and few Republicans.
Second, conservatives should point out that Obama does not have the country's best interests in mind. He does not care about the fate of illegal immigrants -- if he did, he'd stop incentivizing children to travel thousands of miles in the hands of coyotes, then offering uncertainty as to their status, incentivizing thousands more to do the same. He obviously does not care about the political climate of the country -- if he did, he'd stop manipulating and start governing.
Finally, conservatives should ignore Obama. His rhetoric is unimportant. It is a distraction. They should focus instead on his actions, which are deliberately designed to undermine the country for his own political gain.
