Here is a premise:
At a time when Americans are growing increasingly cynical about public service and increasingly disillusioned about their political leaders, McCain charged Saturday, I was disappointed to see my fellow Republicans' reaction to recent comments and writings by Pat Buchanan concerning our nation's role in defeating Nazi Germany.

Here is a hypothesis:
With the new political statements, there is an increase in cynicism across the country.

Is it possible to conclude that if the premise is true, then so is the hypothesis?
yes
