The GOP has long opposed any and all actions of the Obama Administration...and sometimes for good reason. But the current bedwetting against the hypothetical threat ISIS poses to the homeland, exposes the party for what it is.
A morally bankrupt institution focused only on gaining and/or maintaining power.
They bitched and moaned against Obama's inaction while ISIS tore through the bleak, flat wasteland of NW Iraq. They called upon the Administration to bomb ISIS, and some [McCain, Graham, etc] denounced the Administration for not arming "moderate" Syrian forces. Now that the Administration has embarked upon an air campaign against ISIS, and is indeed looking to arm Syrian fighters [what could possibly go wrong?]....they continue to bitch and moan, as if their stated goals were not being realized.
Congress maintains the power To declare War, grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water. [Article I, Section 8, Clause 11, US Constitution].
The House of Representatives could have conducted a roll call vote and called Obama's bluff, long ago. They declined. If the GOP is not going to pull up their big boy pants and act like Constitution-abiding adults, but rather whine and cry like Democrats...why should I ever lend them my vote? They play the same games regarding civil liberties as does the left. If they're going to play bullshit political games, enabled by their media allies...they are in the same camp as the left.
The party is corrupt, bankrupt....and leading the country to oblivion, arm in arm with the alleged 'other side'.
