Oh look. Tom Tancredo is being his usual calm, rational self:

If we go down the road of “not now but maybe later” when Obama is arrogantly daring us by openly engaging in clearly unconstitutional acts, when will it ever by “smart politics” to threaten impeachment against unconstitutional acts by any future president? Impeachment will always be “off the table.”

There is an additional reason we must call Obama’s bluff on impeachment. The time is now, not later, to accept the challenge presented by the threat to “energize the Democratic base.” Are we really that afraid that the Democrat base can be rallied in support of blatantly unconstitutional acts but that the Republican base cannot be motivated and energized to respond in kind? Are we really that afraid to challenge presumptuous dictatorial behavior? If so, then the war is already lost and we should all stock our ammunition shelves and join a militia.
