Well, evil is your word, not mine.
Give it time, you'll see.
To answer your question as to " why didn't they just simply not let Brat win?", quite simply they didn't see it coming. They've got their heads so far up their asses with their own agenda that they no longer listen to the people. They are lazy and full of money.
After all, if any seat is safe it's the majority leader of the house....right??
Here's what I see consistently on this forum.
A) When a liked Republican loses a race to any Democrat it is because of ballot stuffing.
B) When a TEA Party candidate loses to a GOP candidate in a primary it's because the districting is unfair to the TEA Party candidate
C) When a TEA Party candidate wins a primary, it's because the GOP was too stupid/lazy to see it coming, and the will of the people expressed itself.
D) If that TEA Party candidate loses the election, it's because the GOP obstructed his of her victory.
That's textbook Barack Obama blame game.
If Brat and his people can't win this, for whatever reason it is that they can't win, they don't deserve to be there.
If the TEA Party can't defeat whatever obstacles the GOP puts in their path to political significance, then they don't belong in DC.
If they want to convince anyone that they are the political party to lead America in this world, then they have to first prove that they can handle anything and everything that the GOP AND the DNC throws at them, and come out on top.
Russia, China, Iran, and the rest of the America-hating world won't play by the rules either
So they need to quit playing the victim role, quit assigning blame for their failures when they fail, and start putting on the mantle of winners, not whiners.
The obstacles they may face in their way to national power are minuscule in comparison to those they will face after they achieve power.
